Monitor and remove dead websites

[OrKoN]

Hi!

Not all apps are successful and some of them die early.

I have the following experience with the old https://builtwith.angularjs.org/: a friend of mine asked if a real angular app can boot up in less than 2s. I decided to look for real angularjs apps and found this built with angular website. I went through the list and about half of the times the listed app was not available live. That's frustrating and I hope Built with Ember will be always up-to-date or at least will warn you if an app is not live.

Some mechanism to detect out-dated-apps is needed: for example, check the status automatically(show a badge, that the app is not live) and contact the owners to know if it's temporary.

Examples of dead but listed apps I have noticed: http://builtwithember.io/2015/03/09/embersandbox/, http://builtwithember.io/2015/03/09/embersandbox/
