Thanks!
I didn't expect either of What to do with pyblosxom and Busy busy busy to drum up the response they did. I've gotten emails and comments from both entries that were way cool.
As a result, I've finally gotten around to building the flavour registry, I decided I'm going to see what's up and whether I'll work through a 1.1 release for PyBlosxom. We're working through what to do in regards to the filestat callback and possibly moving caching. I started investigating what would be involved in building a regression testing framework (which would double as a performance testing framework as well).
It's been a good couple of days. I really appreciate the advice and encouragement I've gotten. Thanks!
