I'm just the opposite ... I'm voting a lot less
... it seems the points do bias me but in a different way ... if something has a lot of point already, I won't bother to vote it up ... but if theres a really strong post and it has few points I'll immediately upvote it ...
I find it harder to read/skim comments now though ... because I'm reading every comment instead of getting the highlights based on the votes.
I've found that I'm extremely less likely to downvote. And in at least one exchange I've been more civil because it's less of a contest. I think it's a good thing overall but I REALLY miss the ability to skim more efficiently when I want to (I don't always skim but when I don't want to waste too much time it's super helpful).
I have noticed that my karma per post has gone down quite a bit (something that would normally get 7-8 upvotes is getting maybe 1-2 or none). I think it's an example of people thinking "well, someone else has probably voted that up and that arrow is just so tiny".
I'm of course assuming that my posts are awesome and deserving of upvotes, which they may well not be. :)
My guess is, when people don't see how many points a post has, they have no way to calibrate whether it has "too many" points or "too few".
