I just received a gift of 10,000 "fantasy" shares in http://www.minorthird.com on the BlogShares exhange. It's worth taking a look at Minor Third, whose motto is "slightly dissonant, yet pleasing."
Blogshares seems to have succeeded beyond anyone's expectations. For the moment, I can't say the same for the Blogshares Movable Type plugin, which allows one to display BlogShares information on one's site. So far, I have not been able to make the tags for my share price or my p/e ratio work properly.
