Another minor change

For those who actually show up here to read my posts, this won't affect you at all. However, for those that subscribe to feeds, I decided I would try following Google's advice and add 'AdSense for Feeds' to my site. That means that (hopefully unobtrusive) advertisements should start showing up at the bottom of substantive posts (I set a minimum word length, so you shouldn't be getting them on minor posts like this one). If it is distracting or upsetting, though, please let me know and I can see about removing it.
