The Chicagoboyz commenting system seems to be out of order, perhaps due to issues at the hosting company. I apologize for any inconvenience. Whatever the problem is, I suspect it will be fixed before very long.
UPDATE: The hosting company renamed our comments script because it was causing “load issues” on their server. This seems odd, as we have a Turing system that prevents automated comment spam. Perhaps trackbacks are the real problem. Whatever it is I will try to get comments back up ASAP.
UPDATE 2: Ah, turns out the Turing thing only blocks posting but does not prevent the running of CGI processes that clog up the server when a lot of spam comes through, as happened this afternoon. Comments are working again.
