I think having a like button, or maybe have a thumbs up or thumbs down icon would be really neat! It wouldn't bump posts. While I don't see it in the trading grounds, it would be very cool in culinary arts, the trophy room, to be used in guides that people like, and certainly could be fun in pard, sports, and general chat as well.

What do you all think?

i like that idea

thumbs up

even though it might replace all the posts with real comments if they like the topic...

Could be used as rating guides or topic in some forums.
Voted Yes.

Nice idea

Won't happen :

In general no. But I think on a few select forums / threads could be useful.
