Great stuff, but I would like to add to the job site section http://CaribPOP.biz over 100,000 jobs and growing.

what a great resource, thanks.
I will feature it on my blog as well: http://www.emarketingblog.co.za

WOW I agree about social networking being a great business building tool, but I think keeping track of profiles in 50 different spots would be unwieldy. Is there one that is good for keeping track of all of your accounts?

We just launched a marketplace www.linqia.com matching commercial partners/ businesses to key decision makers at Social Networks. There's already 73 social networks reaching over 73 million people globally. Some of the sites you mentioned above have already registered.

YIKES! I was about to put this link on Twitter.. and realized you didn't add TWITTER to the list.. It's kind of THE social networking site of the year I'd think?

F.Y.I ......Furl.net is now diigo.com and Ma.gnolia was closed in early 2009. Did you do your homework and check out these sites before writing your article?

Too many.

I look near the top of your list and I see digg.com. Digg is not an advertising site, it is not a "where's the next up-and-comer" site, and it is not a "businesses that are awesome are found here".

Y'know what the typical digg.com user does? Look for cool shit. You cannot simply MAKE your business show up in a meaningful manner on digg. It happens, or it doesn't.

Your list is flawed for this lack of distinction. Apply liberally.

yourwebchick -- Twitter is listed under General Social-Media Sites.

Good post. It's useful to have all these resources in one place. One point. It's not that easy to create a business reference page in Wikipedia. Wikipedia's (overzealous to some) editors guard against any entry that seems PR oriented. So any business entries will need to be completely balanced -- include negative as well as positive -- to get past the editor gatekeepers.

Sorry, but this is ridiculous. You're a business owner, do you read this list and decide to hire a small army to build a presence on all of these sites? Or, as a busy CEO or President would you take a week off your normal responsibilities to do this yourself? Obama's campaign was great, but let's be serious here. Is that a valuable waste of time or resources? Be strategic. Pick two of them and keep up. Oh and one of the two should be Twitter.

One more niche social media community:

www.upworld.com

UPworld provides a new and exciting way for design, construction, and real estate professionals to meet each other and make valuable business connections online! UPworld is the first website to connect architects, planners, contractors, fabricators, developers, investors, engineers, and suppliers all on a single platform.

UPworld's innovative platform connects professionals to one another for new business opportunities, deals, and projects. UPworld members create online profiles and portfolios to showcase their skills and expertise. They network with each other to establish valuable business connections and form project teams.

UPworld bridges across eight major industries: real estate, planning, finance, development, design, construction, fabrication, and products. Plenty of professional organizations exist that allow architects to network with other architects or developers to network with other developers. Only UPworld helps professionals make connections across industries - and in a global market.

I agree to all of the above, but otherinbox is a must have to keep all those organized and from taking over your inbox. I am signed up for almost all of the above and they all stay in my oib.com where I they are organized by sender in their own mailbox and I can check them when I want to.

even if your business is not trying to actively maintain a presence here, you should be looking on these sites to see if there are already conversations happening about your brand - good to keep your eye out for that.

Great stuff - we love lists of top web 2.0 properties. they are the lifeblood for top SERPS - Discover http://www.the-system.org - how to feed your business with authority

Great list but I agree with Cody Gibbs to some extent. It does take time to manage the profiles, but if you set a schedule and stick to it, it is doable. I would say pick 4 to start - Facebook, Twitter, LinkedIn and one niche group. Schedule 20-30 minutes in the morning, 20-30 minutes in the afternoon. This is free advertising - why wouldn't you make the time? After you get comfortable, you can either rule out the sites that aren't effective for you or move on to another site that may be more effective. And a site to try for managing your profiles is http://www.gizapage.com. Works pretty well.

I'm surprised friendfeed isn't here.

An aggregated feed of all a brand's social shenanigans I would have thought pretty useful/important.

Particularly if said brand embedded a widget of all its stuff on it's website.

Excellent information. I will pass this along to my students.

you left off a new site http://community.yourfindit.com where busiensses and individuals can create profiles using the most popular applications on the web including videos, blogs, jobs, pictures, classified listings, "right now," etc. check it out, its very beneficial

What a great list! Thanks for the great advice!

Use pixelpipe to set them up - its amazing -the future is pipes!

The System

WOW! What an intense list.

How will anyone ever keep up with all that?

One way I've found is to use http://Ping.FM. It doesn't include all those services, but it does include many of them.

I also love my TwitWall that makes Twitter so much more powerful.
=== http://twitwall.com/view/?who=BodyByChocolate

Check out www.KnowEm.com to be able to check your desired User Name at dozens of social sites just like these.

We use it all the time and it's a great reference to see where your brand stands in the social web world.

Well, I wouldn't call them all social sites, and I wouldn't say that the term 'needs' in the title is true, but it's a reasonable list if somewhat out of date.

The power of social media is evident here in all those touting sites that weren't on the list. I must wonder if they are users or employees/owners of the sites, but it is giving the exposure they seek.

To create a unique social media plan requires listening to keywords in various networks and sites. The results will dramatically vary for each company. Start with the conversationprism.com and then establish a conversation index http://is.gd/15K1b based on that analysis.

TweetWagon.com definitely should be on a list of social advertising sites.

All are good sites but instead of trying to canvas each one, I think the best method is to find the ones that apply most to your business and concentrate on them.

Great list. Thanks alot.

Nice list I know of one other freelance job site. www.freelancenation.com I meet Jay the owner at www.blogworldexpo.com 2007 the site is based on blind bidding so that the price of a quality job stays in tacked by only professionals.

Otherwise people would drop there prices to beat others on the jobs making it not worth it to them,this will cause a low quality job in the end.

I would also suggest:
Vreebit.com
www.vreebit.com is a new website coming at the end of July - Vreebit is now accepting pre-signups. If you log on to the site now you can reserve your username and your free website.

Vreebit combines a lot of the features of Facebook, Yahoo Groups, LinkedIn, Google Docs - great for organizing, sharing, and advocating

Ma.gnolia no longer exists and apparently hasn't since early 2009. I never knew anyone who actually used this service and thought it was weird I kept seeing it show up in lists like this. Looks like everyone's still just cutting and pasting.

I think 50 is a great range of options, but far too excessive for any business. Select 5-10 key sites to participate in, and leave it at that. You want to connect where there's the largest relevant audience and a benefit. Some of these sites would have no business benefit at all, not even to connect customers/business efficiently. No company should be spending time on 50 sites when they could be handling customer service in aciton.

One more, just started, powered by wordpress http://wordtaps.com

An important Professional-Networking site is missing : http://www.viadeo.com
well implanted in such countries as France, Italia, Spain, Mexico and more.

great info

Fantastic list of resources.

If used consistently and appropriately, anyone should be able to increase their sites traffic and visibility.

You definity would want to cut this down to what works. When are you supposed to have time to work if you have deal maintaining info on all of these sites?

I have been on some of these sites for years and I have gotten nothing from them.

You also should consider Viadeo. Its a business social network, similar to Linkedin but leader in Europe and China with 8 million members.
Check it through my profile: http://www.viadeo.com/en/profile/julie.laurent

Good post however I am not sure that I would put jobs sites in the 'social sites' category particularly as many are simply online classifieds. Some of those you have listed have a more social aspect to them, whilst others are simply one dimensional job boards.

this article is very useful

This information was G R E A T!...Thank you from those of us who are still getting acclimated to all the techno that's out here...bless you!

Yea this list is hardly a viable list. too many mistakes, closed sites, miscategorized sites. How does Careerbuilder qualify as a social networking site...answer it doesn't it's a job board plain and simple...
So maybe change the title of the article to 50 sites that might be still up and running that have something to do with either socisla networking, marketing, bookmarking or recruiting

A lot of comments seem to stem around not having enough time for a business owner to manage all this. A few points:

1. You definitely do not need to manage profiles at multiple job sites as part of your SEO or Inbound Marketing campaigns.
2. The list of tasks related to a successful Inbound Marketing campaign is larger than this list.

The time it takes is not full time, but it isn't a tiny investment either. It's right in that tough spot where it is too expensive to hire someone for this work, but too much time to pile on current staff.

To that end, our firm offers Managed Inbound Marketing Services, in which we manage all aspects of a small business's Inbound Marketing. Twitter Feed, LinkedIn Profiles and Groups, Blog Postings, Press Releases, Social Networks, Industry Forums, etc.

We charge a price that is based on the value they receive from the program, as opposed to charging relative to what it would cost to do in-house. The value is determined using metrics that are identified at the start of the project.

We think this will enable small, fast growing companies to benefit from social media, while focusing their energy on growing and running their business.

Thanks for the great resource list. Do you know of an application that can manage the greatest number of sites?

Great article and excellent resource. I would love to see any sites/applications to help manage presence on these sites.

Number one, Thanks to the writer for posting this article. Number two, I want to thank some of the people who left comments about other sites that could be useful. And number 3, to those who are concerned about the time it takes or would take to manage these, I will leave you with this.
You should set up all your files that you will want on all of these sites that pertain to you. Then go to each site and systematically download your work, whether it be Blog articles, photos, videos, comments, etc.. This will be the part that takes the longest. After that, you can visit each site once a week to add anything new in your portfolio.
It's sort of like building a house, Downloading all your stuff at first is like building the foundation and structure of the house. The weekly updates are just things you put into the house when you move in i.e.: a couch, a TV, a picture etc...
It seems daunting but if you use your time correctly with tags and such, you will find that you will come up on all the search engines up near the top without buying into ad words or such.
Good Luck

nice list, but as one comments before puts it, just add viadeo, and you'll have all the major ones.

We don't advise that businesses be in all these networks and social sites. It is better to know your demographic and go where your potential and current clients hang out. For example, if someone has a local landscaping company why would they need to be on Digg or Reddit when their demographic isn't there. Better to be connected locally through Twitter, Facebook, Linkedin, and Yelp - maybe even one Green social group and maybe YouTube videos - that's it. If a business is not selling to the world, then why use bandwidth for people who will never be your customers - or even spend time on social sites where there will be no ROI?
Just my thoughts.

I think you are doing a great job with the design and content in this site,I am so interested on what I read and I am curious to find out more about 50 Social Sites That Every Business Needs a Presence On

I'm not sure why people are locked into Myspace, Facebook and Twitter these days when there are so many more targeted social networks based on your chosen profession. IMHO you will meet more of the RIGHT people by using these Social Networks.

Insanity Workout

I think it's important for people to target the social networks based on what occupation they are involved in. You only need to meet a few of the right people to make a real difference in your career, so it only makes sense to target the right social networks.
