I know of at least one reader who's having trouble getting Blogger to publish their comments. I think it's just an isolated incident, but if anyone else is having the same problem, feel free to email me your comment and I can post it on your behalf (subject to the possible delays noted below).
P.S. This time tomorrow I'll be flying over the Pacific. I don't know how long it'll take me to settle in and start posting again, but in case of delays, here's an open thread for commenters to contribute their own content. So: what's been puzzling you lately?
