> I find it very interesting that the main competitor to Wikipedia which is Grokipedia

Encyclopedia Britannica (the website not the printed book) is the main competitor to Wikipedia and gets an order of magnitude more traffic than grokipedia. Right now grokipedia is the new kid on the block. It has yet to be seen if its just a novelty or if it has staying power but either way it still has a ways to go before its Wikipedia's primary competitor.
