Edit, just noticed it's a Thumbs Up count for the opening post only, rather than the whole thread. Still would be useful, and if it could be amended to the whole thread that'd be even more handy.
I use a forum that has the total number of thumbs up on the thread displayed to the left of the thread title on the main page. That way you can instantly notice threads that are obviously very popular , thinking the KazArt one in particular, and are less likely to miss the really good stuff.
