Steve and I had the privilege of giving a keynote at last year's PyCon. Watch the video [steal slides here] for Steve's gripping account of the switch from Lisp to Python, see him artfully respond to questions about why reddit's search is so unsatisfying, and hear me get asked if I'll sponsor PyCon the following year (it's near the end of Q&A, when the audience decides to give Steve a respite). I said yes, albeit while put on the spot, but it was a "yes" nonetheless.
I aspire to be a man of my word, so if you're attending PyCon this year, be on the lookout for the breadpig booth (a very nice perk of "Silver Level" sponsorship, I might add) where we'll be selling xkcd: volume 0. (Don't worry, if you're at a Python convention, yet don't already have a copy, we won't tell -- plus, you're saving on shipping costs, which is prudent).
Breadpig is proud to be sponsoring PyCon, especially given all that the language and community have done for reddit (open-source, btw!). Donating $3K to this foundation is just a small way of saying thanks.
