Here are a couple of writings in a more-than-a-blog format related to our projects or to software in general:

Rapid Software Evolution

is a piece, written in dialog form, about human-driven software evolution, why it is important and how it might be done. A writeup of the same ideas for the International Conference on Complex Systems 2007 can be found here. And PowerPoint presentation given at the Miami Java User Group can be found here.
