Profile editing

Hi!

There is a profile page for every user, but there doesn't seem to be much that can be added to the profile.

As a developer, it would be nice if my applications would be listed there. It would be also nice if I could add some text describing myself there.

This would be very useful as I could point to this single URL to other peopl, rather than posting multiple links to them.

On my profile there is currently a link to my Twitter account but I am not able to edit it. Was this something which was present previously and then withdrawn?
