Steve, I have to agree with you. I personally don't want to be "known" as an official representative of CDC - my job doesn't define my activity on GovLoop. I just happen to work for CDC, a government agency.
I like the badge and tag cloud ideas. I would also like to upload my own badge designs to represent me, (in a business capacity).
Joshua, I do agree that this should not turn into a MySpace. I would include the same type of info that I would share with those on LinkedIn; however, my discussions are not as formal.
