Why MetaFilter is Awesome And Why the World Needs to Know [more inside]
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.
