>(I also wish we didn't display post score. I don't know what it provides as a benefit.)

That would be an interesting experiment. However, I think it does provide a certain use, which is getting a sense of how people are perceiving the discussion. Like the audience clapping or booing during a debate.

I would rather know what other people think after I decide what I think. Nothing is contributing to groupthink on this site more than the fact that we don't use blind voting.

That's what I was thinking. I hate seeing what other people think of opinions before I see them. Furthermore, they offer an "equalling" incentive: perhaps I'm the only person here that thinks like this, but if I see two points, and they're both well-argued, but the one I disagree with is rated higher than the one I like, I'll either vote up the one and not the other, or, if the one I disagree with is very highly rated, I'll vote it down to bump the one I like higher. The psychological impact of seeing the point I made go higher is one that modifies my voting patterns, which I don't like.
