Guido van Rossum steps down as BDFL of Python project. Sounds like he was not having fun any longer... Quote: “I'm tired, and need a very long break.”
@Kensan Judging by his e-mail, I'd say he has been finding himself increasingly at odds with the greater community anyway. His words: "fighting" for a PEP that, frankly, looked like it was common sense.
For better or for worse, you're not a dictator if you have to fight with your community to get something adopted. I think Guido finally realized he has more important things to do with his time, and I can't say I blame him.
