Re: Whats with the thumbs up/down?
It used to be up there under your name, but now you can only see your rep points on a persons profile page (the green bar to the top right).
I think a while ago you used to be able to give positive and negative rep points, but it's only been positive since I've been here (roughly the same time as you under similar account). I think they ditched it b/c people were getting out of hand with it. I wouldn't care really if it was taken back to normal, but that's not up to me.
Look at these eyebrows. These are attack eyebrows! They could take off bottle caps!
