Spam Diet

I'm going on a spam diet. I've gotten, literally, thousands of spam comments this month. So I'm shutting down comments on old posts. I'm not sure how current I'm going to go with shutting off comments thing but right now I'm only in September 2005. I'll try to do this periodically to see if it helps the spam situation. I may only keep a couple of months at a time open. (Of course this requires regular blog maintenance and we all know how I'm so not good at keeping up with such things...)

EDIT: I hate going back through and rereading things I've written. I frequently want to rewrite them. Is this normal? I'm sorely tempted to rewrite some posts...
