If the site is meant to be a joke, it's so subtle that only the authors and their inner circle of friends are really enjoying it.
The ridiculously positive reviews could be taken as a sign it's a joke, but most of the site is totally believable if you imagine some ultra-fanboy is behind the whole thing.
Edit: then again, when all is said and done, who cares? If the site wants to be taken seriously, a few more undeserved 10/10s will quickly destroy its credibility.
