Structural Changes
For ease and speed, I'm fine with the structure of the boards.
I like the idea of putting faces or avatars or logos with people, but think that may slow down the speed of the boards. (You always can link off to a profile page elsewhere on the MySpace/Facebooks of the world so you can be "seen" there.)
However, while 3-letter search is now allowed, I think the overall search feature on this site is still in need of an overhaul. There's tremendously incredible content deep within the site, but trying to get to it is extremely painful.
