This question already has an answer here:
This website is somewhat similar to StackExchange websites. It has a very similar structure.
But there are some details which differ (the URL structure, no hyperlinks at the bottom of the page, ugly voting hands instead of nice arrows, not speaking of the UI design itself), besides I couldn't find this page in http://stackexchange.com/sites.
I wonder, does it have anything to do with StackExchange (hope not)? Or is it just a not-so-well-made copy?
