I’ve started writing a post or two per week over at WordFrame.com. My first post is Vertical social networks for business, a table of their own, which reports on the new eMarketer study about businesses entering the social network space.
(BTW, WordFrame is an awesome B2B social networking platform. If your company has an interest in creating a socnet for either internal or external use, I recommend it highly. It’s affordable, highly scalable and has all the features you’d want or need.)
