I set up a contextual ads thing with Amazon on the site. This causes certain words in posts to be linked to products at Amazon.com, so you might notice this in some posts. It seems to be completely random at linking to things.
If this is too annoying or causes problems, please tell me. So far I haven't noticed any issues with it, but it's only been up a few hours. If it sucks too badly or annoys the hell out of everyone, I'll take them down. Or maybe just make it so only guests see them.
