Well, maybe not a star, but who knows? You will certainly get to meet a lot of interesting people with a common interest in Guido van Rossum's invention. And sessions are televised. Last year I posted two months after PyCon to point out that there had been 180,000 views of PyCon-related videos on blip.tv.
Of course it's too late now to be a speaker at PyCon 2010 if you haven't already been accepted - those decisions were made a while ago (with great difficulty, as there were so many excellent submissions this year).
It would be interesting to hear from some of the quarter of a million people who've viewed the PyCon videos just to see what you thought was good and bad about them. They certainly make information about Python much more readily available.
The people who speak at PyCon (and the many other Python conferences throughout the world) are stars anyway, in my opinion, and deserve our support. They are giving freely of the experience they have developed, and they deserve our thanks and recognition. PyCon speakers don't get free registration or much else in the way of reward, so when you are at the conference (or if you come across one of them elsewhere) please let them know how much you appreciate their work.
