Sorry for bothering with this kinda silly idea, but I can't get it out of my head. How about making a simple "like" addon associated with posts in a discussion? Call me facebookian, but I've seen it on vBulletin forums as well and it seems to improve the quality of the discussion.
I really want to write one myself, but the lack of skills and time keeps me from doing it at the moment. Anyone else up for it?
