Nothing earth-shattering, just wanted everyone to know that we now collect screen names. For the moment, these are just AIM, XMPP (aka Jabber) and Twitter. If you want other services added, let me know. I'm also not doing anything particularly special with this information right now, but some future possibilities are:
Automatic Twitter feed on profile page.
An online/offline button for XMPP.
An API or search tool to find out who owns a specific account.
I haven't thought through privacy concerns about any of the above, they are just random ideas thrown out there. Feel free to throw in your own!
