What do you guys think about instituting "personality points" towards users? You know, something along the lines of: 15 members think user x talks out of his ass too much. 6 members think user y suffers from a holier than thou complex. 24 members have been helped by user z. etc. Really, it's all about helping create context, especially for new and less frequent users. I would love an option where I could scroll my mouse over a name when I read advice in an AskMe thread and see something like, "173 users recommend against this user's advice." It could be all spelled out in a user's profile next to the "this user links to" category.
The New York Times' Online Diary (scroll down to "I'm Paul!"): Online personality tests are a long-running Web "meme," or viral idea. No mention of MeFi, or how agonizing tests are, or ways to cure people's obsession with the danged things, but you can't have everything, I guess. [Login: metafi/metafi; pony not included.]
