Jason just posted in our forums about a new site called SocialPicks (announcement) which allows users to rate and review stocks online in a Digg-like social fashion. This could be a really interesting experiment in social investing. Will it lead to finding more undiscovered stocks or will it be abused and go to prove that there are few free lunches on Wall Street?
I also found a post on Mashable.com that is touting DigStock, another social-based stock community.
