Doesn't it suck when you discover your site is down because a page went popular on Digg? Wouldn't it be nice if you somehow knew that your site is slowly inching its way up the upcoming list? And what about delicious? That could be a serious hit of traffic too.

Well now you can get a warning. Over the past few months, I've been slowly building a service called Social Alerter. Social Alerter is a free service that alerts you when your websites are about to go popular on Digg and delicious. You can monitor as many sites as you want and once it finds one, it sends you an email. You can use it to monitor your own sites, your competitors' sites (ha ), and your favorite sites. You simply sign up and know that there is an eye out doing all the leg work.

This is the service in a nutshell. I've written a huge help section and if you read just one page, read the Social Alerter crash course.
