XMPP for carbon lovers
If you happen to be a dead-tree-addict, and interested in XMPP like me, then I'm happy to tell you that you will have a present next year.
Kevin, Peter and Remko are hard at work for O'Reilly to brings us the XMPP missing book.
Entitled "XMPP: The Definitive Guide", it should hit the shelfs in 2009.
Shameless offer: if you need technical reviewers, you know my JID :).
