Code Update

I updated the code for the site (no more errors!) and either did something really right, or really wrong, as traffic has dropped from 20,000 hits/day to roughly 6,000 hits/day. Perhaps it has something to do with spidering robots, or with changes to my robots.txt file, or with the httpd.conf changes I made (I was playing with denying access to particular IP addresses - porn referrer-log spammers), or maybe something else?
