twitter isn't as big as i thought it would have been. unless it doesn't inclue the new accnts made this and last yr.

I think this is the new result, because Facebook is 300,000,000

Social media, in one word, awesome! Unbelievable growth and still...so much untapped potential out there. We have only just begun.

Facebook is now at 350,000,000; but the Twitter number is pretty close to correct. These stats are probably a month or two old, is all. Twitter's had huge growth because it started this year at around 14,000,000 -- but its still relatively small by social networking standards.

Despite all of the free promotion from TV news shows, Twitter isn't particularly popular outside of the addicted power users, mainly because it's completely non-functional outside of its basic "chatroom" experience. If it grows passed 100,000,000 I will be surprised.

How many actual Tagged.com users are there, tho? Remember they HEAVILY inflated their user figures because they were SPAMMERS.

twitter should more bigger, ? alexa ! check ur data=?

Despite the comments regarding twitter i think, it is the perfect base for any e-marketing campaign, that you can link to all social networks, sites and all kind web ad and promos you want to deliver to a specific audience, so i think this is just the beginning for twitter.

Wheres Asianavenue?!?

Super

Where is xing.com? Formerly known as openBC?

Very fun to see graphically done. Thanks! Trina

Where is Bolt.com on this list? I recall it being the original MySpace - it was huge around 99-00!

I am not crazy over twitter at all. But the alternatives are worse.

An otherwise well done infographic, it has a major gap by not including SixDegrees. While the site ultimately failed, more than any other site, it pretty much created the "social network" model that all the subsequent sites have built upon, had over a million members and was started in 1997.

Great article. Amazing how the giants fall so easily....

impressive graph.

you could have added :
Stayfriends.de : 9 million users, founded in 2002 (Germany)

update :
Trombi.com : 6.8 million users

To be fair Charlene, Twitter has gotten pretty big in just a 3 year span. Compare their growth to MySpace and Facebook over the same time periods and you will see that it is on par to those behemoths.

Their next barrier is finding a way to generate revenue, not customer acquisition (even though this is always an ongoing process).

It's cool to see the list start with Classmates.com. Randy Conrad, who was a high school classmate, started it because our high school was on a military base in the Philippines and after we came back to the states, it was hard to locate everyone. We had all dispersed and many of us hadn't kept in touch with each other.

Classmates.com was my first experience in being able to reconnect with people I hadn't seen in a number of years and never thought I'd find again.

Your are missing SixDegrees

What about stumble upon?

This is a *terrible* visualization. It says nothing about how these sites have grown, it depicts population size (captured ....when, exactly?) with circle radius (or is that area? - ouch!) and uses color to encode..um....what exactly? This is like a case study in what not to do.

The progression for the surviving sites like Facebook and Twitter, will be able to see if they can successfully move to more profitable financial models. It appears Facebook is heading to an IPO.

This is a very cool infographic, but I agree a bit with MattC's complaints (although not the way he delivers them).

As far as I can tell, the colors don't have any correlation with size. Is there another characteristic they represent?

I assume the timeline represents year of appearance and the numbers represent current (if still active) or peak (if defunct)?

It would be nice to see some notes on which sites are active and which are defunct. This could've been accomplished with the colors.

For the American audience some notes on the foreign social networks would be very helpful.

A key would've been helpful to decipher this infographic a bit.

Notes for version 2 perhaps?

Otherwise nice work!

It's cool, but in terms of value none of them really present anything significant.
It's only a matter of time before facebook is passe and the idea is tired.

Wow! The common denominator is that people are meeting people! That will never change.

Where is Wordpress.com?

Amazing that there is social networks bigger than Twitter that are completely unknown to me at least. Interesting!

What about Farmville? Heard some figs that is is huge... Or is it under fb?

I guess Twitter has more registration than this table shows, however there are people, including me ;-), who have more than one account
