Well, it was bound to happen.
I got a job offer. A great team of people I like offered me a change to work with some cool applications, and it will still be related to XMPP. The language will change but that's ok, because I also like Ruby :).
So sometime in the next couple of weeks I'll be starting to work at 37Signals. I wont talk about what I'll be doing, expect mentioning XMPP.
PS: BTW, today is exactly one year since I joined Sapo.
