As long as I've been blogging—fifteen years, off and on—it's been mostly a personal exercise, an attempt to work out my thoughts on a number of subjects by writing them down. When I started my first blog in July of 2005 I had no trouble finding topics to write about, and was constrained only by the time available to write. As time went on, I began to realize I had said what I wanted to say about most of the things I wanted to talk about.
