Since I wrote the blogging engine used by this site myself, it lags a bit behind some other blogs in terms of features. I specifically chose to do this though since it allows me ultimate control over the look and functionality of this site, and give it a few unique twists (for example: there are, as far as I know, no off-the-shelf blogging engines that do the AJAX comment loading and calendar that I have here).
I've been working on getting some of the gaps filled. In the past week I've added post categories and more friendly URLs for the individual post pages. Also new is that the calendar now shows the number of posts for that day if you hover over a link (it's rarely more than one, but still). I've also fixed some bugs and improved the code in many places, which should make for a better experience all around.
