Cleaning House: Spammers Raining On Our Parade

Due to an enormous influx of spam, we've turned on the CAPTCHA requirement for comments.

What is CAPTCHA?

Update:
Apparently the spammer is able to get by CAPTCHA, so we're going to require authentication for a little while until we get this problem fixed. Thank you for your patience!
