Monitor any web site for changes

I found a pretty cool web site today that allows you to monitor any web site and have an email notify you when it changes.

So what is this good for?? Lot's of things.

I was looking for something that would let me know when a list of known vulnerabilities for a piece of PHP code that we use is updated. This list is kept as an HTML file with no way to subscribe or add the page to my RSS feed reader. So now anytime there is a new vulnerability, I will get an email. Cool.

It also has a webmaster control panel that allows you to add a widget to your site that visitors can use to be notified whenever you update your page. I personally use RSS for this on my company web site but there a lot of people who don't use RSS. So this allows them to automatically get my new content by email when I publish it.

I plan on testing that functionality to offer to some of our clients.
