This is the bi-weekly open thread. Post about anything you want, ask random questions, whatever. Also:
1. Thanks to Douglas Knight, who proposed a new system of open threads I think I’ll be using from now on. There is an Open Thread tag above. When you click it, you will be taken to the newest Open Thread. Once every second Sunday, the Open Thread will be posted publicly on the main blog like this one. On Wednesdays and the other Sunday, it will be posted quietly and appear only if you’re looking for it in the Open Thread section. So you can find a new Open Thread there starting this Wednesday the 25th.
2. I don’t plan to introduce Reddit-style voting on comments here because most people have said they don’t want it. If you do want it, there is a Greasemonkey script available that will let you have it, without affecting the comments viewed by everyone else.
3. I finally gave in and banned email@example.com; abuses were just getting too annoying. Sorry.
