I am slowly but surely adding tags or "Labels" to our posts. I've made it through about 500 posts. Just 2300+ more to go. (Yeah, I'm not sure I'm that motivated.) The labels serve as an index; they're an additional tool to help find things. Feel free to add or edit tags.
Update: Two things:
1) I've been inconsistent -- whimsical, really -- in choosing whether to tag a post liberally or sparsely and whether to include the topics that appear in the Comments. Do not try to infer rhyme or reason; there is none.
2) I believe we can "hide" the Labels on the posts, so if you don't like the way they alter the look of the blog, we can fix that.
