I have a new CGI book event page up. I've had it sitting around for a while, but I never actually told anyone. I just finally added the redirect, so my CGI book event page is now the default at http://scottstuff.net/books, instead of PHP iCalendar. The iCalendar version was easy to put up, but it's painfully hard to read; the new one should be quite a bit better.
If you're still using the PHP iCalendar-generated RSS feed, you should really flip to the new one. It has better detail, and it's not such a huge hit on my poor server. I'm probably going to kill off the PHP one eventually.
