Ugh. Over the weekend, the DNS provider for abstractioneer.org helpfully upgraded their software... and the new code refused to let me make abstractioneer.org be a CNAME for ghs.google.com, claiming it's illegal. (No, it's not, it just keeps you from using mail to that domain and a couple of other things, none of which I care about.)
All of which means that (a) abstractioneer.org is now www.abstractioneer.org; (b) my OpenID has now changed, with the old one (abstractioneer.org) doing a 302 redirect to the new one (www.abstractioneer.org). I'm viewing this as an experiment; let's see what breaks.
