Fixed now - thanks so much!
Folks - a couple of people have setup their systems to refresh *all* our category feeds every five minutes - this is putting an undue load on our server (and screws up our server stats). I know I post a lot but not *that* often. I've WHOIS'd the IP addresses - one person is in Brazil and another in Korea - I can't limit how often you do this but I can ban your ISP's IP addresses if you continue to put this load on us - which I don't want to do. Please change your refresh rate to be 60 minutes or just subscribe to a whole blog feed rather than all the category feeds.
Thanks!
