FYI, some colleagues and I will be presenting at the Austin Python User Group (APUG) meeting tomorrow night (Wednesday, September 10th) at 7pm. We'll be talking "behind-the-scenes tech" for one of the high-traffic Django-based sites we've been building over the past year.
For directions and more info, see the APUG wiki: http://wiki.python.org/moin/AustinPythonUserGroup
Hope to see you there!
