While not solely MR focused, these are a few of my favorite (outside of the Cvent blog of course!)
1. Customer Experience Matters by Bruce Temkin: http://experiencematters.wordpress.com
2. Research Rockstar by Kathryn Korostoff: http://www.researchrockstar.com
3. Deliver Bliss by Tim Sanchez: http://deliverbliss.com

I think Sean Copeland put together a great list at the beginning of the year as well. You can see his top 10 finalists here (I intentionally left blogs listed here off my top three list): http://www.seancopeland.me/2010/12/top-market-research-blogs-of-2011-10.html

I'm happy to say Cvent's Web Surveys blog ranked #3!! (http://survey.cvent.com)

There are tons of great blogs in the MRX space. Here are a few of my picks:

1. I would be neglecting my duty if I didn't mention Verbatim, Communispace's Market Research Blog (http://blog.communispace.com/), featuring articles like "What Makes Market Research Valid?" to "5 Market Research Online Community Case Studies" to, yes, even "Why do we Want to be Bears? Anthropomorphic Ethnographic Research in Action".

2. Tom H.C. Anderson's Next Gen Market Research Blog (http://www.tomhcanderson.com/)

3. Forrester's Market Insights Blog (http://blogs.forrester.com/market_insights)

There are so many different blogs out there it is hard to establish which ones are good and which ones aren't so useful. I have found that myalltop is a great facility to find latest and relevant articles and blogs. Its hard to identify any outright favourites but I often find the following three have up-to-date informative articles and blogs which are extremely interesting smallbiztrends.com, realbusiness.co.uk and entrepreneur.com

Similar to Sherrie I am also happy to say that our website Marketest have a great blog which is updated everyday!
