What do you guys think about a "Thank you" button? Most of the forums I'm in have it, so I thought I could suggest it here as well.

I think this simple feature would add some interesting dynamics. People would be motivated to post usefull stuff to "collect" thank you's, for instance. It would also help avoiding "Thank you" spam posts.

I realize that there are more important issues for the dev's to deal with, but I wanted to post the idea anyway.
