Odd feed behavior

By the way, I noticed that my blog feed was exhibiting odd behavior and showing very old posts as if they were new. The reason for this is because I've been going back and re-editing all of my old posts. Blogger just installed this nifty new feature where each post can be assigned to one or more categories, and if you click a category at the bottom of the post, you can see all posts in that category. So if you want to see everything I've recently blogged about, say, atheism, or grad school, just click the label and it's all neatly sorted. I like it.
