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!
