Thanks. And I'm not forgetting that you played some part in getting me
into the poster session business in the first place... ;)
We'll be issuing the poster session CFP around the same time as the
regular talk CFP, and I really hope some edu-sig-ers will consider
proposing a poster. The whole idea behind posters at PyCon, IMO, is to
give a voice to speakers and topics that otherwise wouldn't make it
through the tough competition of regular talks, so don't be shy.
And it was quite frankly a blast! If you weren't at PyCon it's hard to
describe the super-mega-hallway-track-on-steroids atmosphere that
developed. So start working on those posters!

Yeah, I gave a talk to a group of Pythonistas in Indy last week,
http://learnpython.wordpress.com/2010/06/26/indypy-meetup-and-python-3/
focusing on Python 3.x. They were an accomplished bunch, but not very
familiar with 3.x, except for one who was excited about the use of
Unicode, particularly in source code. His observation was that it made
Python much more accessible for speakers of, say, south Asian languages.
And yeah, I did mention your experiments along those lines.
There are some in the Python community who think that having to port
things to 3.x is going to sap the fun out of the language. I don't agree
- Python 3 is (deservedly) the language of the future and the future
WILL get here. ;)

And I gather that at least one class at UCLA is using my book, which is
solely Python 3.x (further book info in my sig).
Cheers,
