Apologies to readers, especially those who comment: I'm turning on this blog's captcha comment requirement. We're getting hit hard by comment spammers. Junk notification, IP banning, ruthless monitoring haven't staunched the slimy flood.
So please do the human thing and interpret the block of weirdly fonted text when you comment. If you have any problems, please email me.
Bah. Death to spammers.
