According to Tom Pick, Virtual Hosting Blog has picked the Top 100 Social Media and Social Networking Blogs for 2007, and SMC was one of them. (I can't confirm this as Virtual Hosting blog is having an error on that page at the moment.)
Lots of credit to Chris Heuer, for setting this whole deal up and writing some great stuff, to Jason Chervokas, who wrote some excellent pieces for us this year, and of course, Francine Hardaway, Connie Reece, Kristie Wells, and everyone else who contributed to making the SMC blog a useful source of information in the field.
