I don't know if anybody pays any attention to those category links over in the sidebar, but lately I've been wondering about their usefulness, or lack thereof. In particular, I'm thinking that a couple of the categories -- "General Ramblings" and "Esoterica" -- have degenerated into catch-alls that cover way too much ground to really provide much of a service to anyone, including myself. So, in order to give these things a little more functionality for anyone who may actually use them (not to mention improving my own sense of organization), I've decided to experiment with creating some sub-categories. The first of these, "Final Frontier," is now live and ready for your perusal. It encompasses, as you may surmise from the name, all my entries relating to space flight or space exploration (as it turns out, that's about half of the content that I'd previously filed under "Esoterica"). I've gone back and re-categorized everything that fits under this new heading, so you should be able to quickly scan my ramblings on what goes on "out there," if that's a subject that interests you. I have a couple of other sub-categories in mind as well, and I'll be adding them as I find the time and inspiration.
As always when I make a site change, let me know in the comments below if you have any strong feelings one way or the other. Also, any suggestions for sub-categories (or top-level categories, for that matter) are welcome.
