you know it's not a bad idea when ya think about it. it's something like google would do except not use it to take over the world.
log user data and display most relavent information based on what they look at the most and search for on the forums. Have those subjects and tags etc on the side and allow the user to delete them from their interests. i might be interested in n900 rebooting bug if i have it and then not interested when it's fixed. so those threads are lower down with the rest of the stuff i'm not that interested in yet.
