Over one thousand registrations are in the system for PyCon 2008. Over 2**10, actually. Amazing!
After exulting a bit over that kind of growth, I moved on to worrying about whether PyCon can keep the magic that makes it so great as it grows. A look through the still-forming Open Space schedule quickly reassured me. For instance, Steve Holden has scheduled an Open Space session called "Teach Me Twisted" - not because he knows Twisted, but because he wants to learn it. So he's challenged the Twisted community to come and teach it, and it looks like they're responding.
Learner-driven content - I love it!
