I have added the ability to give a post a Thumbs Up/Thumbs Down rating. Let me know your thoughts. My only concern is that people will get a lot of thumbs down if they don't share the same opinion as the majority. I personally like hearing different opinions. It is a big reason why I started the site.
So no promises that we will keep it, but I thought I'd try it.
Edit: I have removed the thumbs down option so that we can avoid the issue I described above.
