I agree with this. I think I suggested it in the times of old, and again with this recreation, but it was never done. I think it might be part of the user profile updates once the project is almost done.
I don't think Alex will add it to the project. His focus seems a lot less on the user-based scheme and a lot more on content display.
P.S. Isn't a bad thing, but he just seems a bit focused ;]
