It's nice and cool, but I don't like the idea of promoting a website that just copies wikipedia. Also, there are not sooooo many "cool features" as you imagine when you read the description.

Cool idea, nice style, but it's not an extension. It's just a different website with contents taken from Wikipedia.

Awesome. :)
