I think the "Thanks" button was a great idea. I would like to propose a "Co-sign" button. So that if someone has a problem (or whatever) and a solution is offered everyone else who agrees with the solution can "co-sign" the post. That way when looking for solutions if a post is Co-signed by a half million people then it must be a good solution.

I was on a thread and saw some info I agreed with and I wanted to post on it but it simply would have been an "agreed with above" but rather than post a nice "co-sign" button would have been great.

I already use "Thanks!" this way, and others do as well.

Also, this may have gone better in "Comment/Suggest".
