Aaron Strout, VP of Social Media at Mzinga, wrote a great guest post on ZDNet which resulted in some rather silly drama.
The original post is about whether it makes sense for companies to build their own branded communities or to build a presence on existing public social networks, or, as he recommends, to do both. Apparently the post flushed out some kind of troll who claimed the rights to the term "branded community". Good luck with that one.
