Thanks for your comment! There certainly could be. No way to know for sure as I can’t see everyone who is on Buzz. I do follow a number of people who work for companies that have an online presence. It is partly by watching and interacting with them that I came up with the guidelines in this post. The ones who are doing it right, in my opinion, have established credibility and authority in Buzz but rarely trumpet their own business. When they do, it’s via posting interesting and useful articles or posts from their company (and of course, they have their corporate brand prominently displayed in their profiles). Where I in the market for services they perform, I’d likely turn to them first as they’ve already established relationship and credibility with me.
