I like minimal profiles that let the user do whatever they want. No reason you couldn't turn your resume into txt and stick it in your profile.

I'd love to see a form of official "Ask YC" category, with a subcategory of "Review my App" -- make it so it requires n karma to post to [to prevent spam] and then we can easily see what all hackers are upto.

If we can see what other users are working on -- that'll encourage us to click their profile.
