I really like the idea here, but I've encountered a problem using it. I think all emails from the service must be getting spam-filtered before they reach me. Because (a) I've never had an email with a settings link, like the one discussed on this thread, and (b) I've not been notified when my site has been down (which, recently, it has). I know I entered the email right: when I enter the same email and URL, I'm told the URL is monitored for that email. And I can see your hits in my Apache logs every 15 minutes. Obviously, my spam filters are not your fault, but they do create an annoying problem: (b) means the service is useless for me, and (a) means I can't cancel it! So it seems I'm obliged to take 4 pointless web site hits an hour forever (short of blocking you with iptables or some such). One way round this might be for you to require people to click a link in a confirmation email in order to start monitoring, but obviously that does add a precious click to the sign up process.
