The main page has a box about the chat thingie. No one seems to be using it for anything---I just went into the "room" and it appears the last time someone said something there was 10 days ago... Could it be moved somewhere less prominent? The main page is quite busy already!
(The tag list and the recently-awarded-badge list are also sort of pointless IMHO... When I asked about them on MO, they were removed and I don't think anyone even noticed.)
