1) Restructure the forums so that it is possible to read 'by platform/OS' (example: right now the 'Applications' forum doesn't have any device-subforum which makes it often very confusing if a discussed app is for Diabo, Fremantle, etc) - and for people who is just interested in say OS2008 it is hard to filter out the other posts.
6) Retire the Karma system People are 'thanking' way too much because they like the person or agree with the positive/negative spirit of a post - not because the post is particularly useful.
7) Implement 'thumbs-down' for posts Implement a way to rate a post 'thumbs-down' and an option to read the forum 'community-moderated' where posts with X thumbs-down would be auto-suppressed.
