I've had several people tell me comments were not working the last couple of days.
It turns out two problems were happening at the same time.
My ISP's DNS servers are freaking out about something and not fulfilling requests, and my blog could not successfully find Akismet to verify comments with.
OzzFan originally reported the problem but I had forgotten I was already logged into my blogging software and so it doesn't run my comments through the spam filter.
I have switched my machines over to using OpenDNS DNS Servers, Akismet is still giving me a problem though so I have it disabled for right now.
Sorry about the problems everybody, I wasn't intentionally blocking anybody from posting anything good or bad about me or BOINC.
