Today is the last day the registration page for PyCon will be up! You can register at the door, though, so even if you *really* procrastinate you can still come.
If you look at the attendees list you will see that as of this post there are 552 people registered! This is going to be one hell of a conference! Should be tons of fun. Maybe we will even have a decent amount stay after for the sprints. I am really glad I am sticking around for the whole week.
