i just noticed a new feature today... not sure how long it's been there.

usually i use "add this" in my ff browser to share discussions, but it's nice to see the facebook like and twitter tweet buttons on the threads! that way we can more easily share the discussions that really hook us!

following the last entry of the discussion thread, there are buttons that allow you to print, mark read, follow, add to rss feed, share/like on fb or tweet.

sorry it took me so long to notice that, just thought i'd mention in case anyone else missed it as well.
