Twitter support in JabberStatus
JabberStatus was originally inspired by Twitter's facility to update your status via XMPP/Jabber. Unfortunately, Twitter's Jabber interface has been down for months now, which is rather sucky.
The solution to this? Extend JabberStatus to work for Twitter as well as Facebook. It turned out to be very easy, so it's online now. Just add email@example.com to your contact list and it will talk you through the rest.
