minor site updates

If you've visited the site recently, you may have noticed some cosmetic and usability changes. If you haven't, they're not earth-shaking, so you needn't drop everything you're doing and check it out! (Though, I mean, you can if you want to. Don't let me stop you.) I do hope they will make the site better-looking and easier to use.

Notably, the tag cloud, which was hanging out, unstyled, at the top of this main content box, has moved to the sidebar to the left and gotten some styling so it looks like an actual tag cloud. Also, the site now has an actual archive, also quicklinked in the sidebar to the left, and I've gone back and mostly fixed the organization of the early posts, so everything should be easier to find now. (Though not too easy; some of that stuff is embarrassing. We were freshmen once, and young — in high school, even! 😉

Please let me know if you encounter any problems.
