It occurs to me that it's about time to repeat the rules for commenting. In particular, I'm going to start taking a heavier hand in deleting off-topic comments and simple personal attacks. I'm happy to house all the disagreement folks can handle, but I'm committed to keeping the comments a useful and interesting forum for discussion, as those exchanges are make writing this site fun for me. As always, if you feel I've deleted one of your comments in error, my e-mail is right there on the sidebar. You're welcome to appeal.
