Just a quick administrative note. For the last few days, there’s been a huge increase in spam comments. As a result, I’m tightening up the spam filters to prevent them from getting posted even for a brief period. As a result, legitimate comments may take longer to appear. If you have a comment that should have appeared, and it still hasn’t shown up after a few hours, feel free to send me an email, and I’ll bounce over and release it as soon as possible.
