Reddit (the front page of the Internet!) has an interesting feature that attempts to explain selected topics in simple language. Reddit is a sort of modern version of the old bulletin board systems that were around at the dawn of the Internet.
The feature (or "sub-reddit") is referred to as "Explain it like I'm five", or ELI5 in abbreviated form. While the quality of the posts vary, and some are pretty obviously "taking sides", it's a useful tool to get an insight into "heavy duty" or technical topics like Steve Hawking's New Theory On Black Holes or What Is A Straw Man Argument?
