Previously, I asked about a feature request for adding a batting average, as a tool for giving more info on the person supplying the answer. From the answers given, it seems like I've been putting too much importance on the rep score - it shouldn't be taken seriously, it's just a number, judge answers by the answers, etc.
As a new user I simply associated a high rep score with expertise. Since we should be judging answers based solely on the answers, I'm thinking that having the answerer's rep score (and badges, too, by extension) appear under the name on an answer are misleading - it influences other people's participation on the site (both the questioner and other answerers). This is a contradiction - if the stated intention of the site is to develop quality answers, then it should not allow non-question-related information to influence or bias people's participation on the site, right? How about just hiding those bits of info on the various answers?
You could extend this argument to say that even the username of the answerer be hidden so that answers appear anonymous on the question page - individual user's profile page could still list everything as it is now for interested parties...
