I just enabled clean urls, which takes the ?q= bit out of most urls. This makes linking to certain things (like your profile) easier. Compare:
Default URL Scheme:
Clean URL Scheme:
Simpler is better. Let me know if anything breaks. It might take a while for this change to propagate and your browsers might still have the old URLs cached. But, over time, the "?q=" should disappear (I might need to edit some of the nav links by hand, though). Both URL schemes should continue to work indefinitely, as far as I know.
