I think it's an interesting concept, but by nature, it can't be trusted any more than Amazon reviews can. I'm certain the intentions are good (giving the benefit of the doubt) but it won't be long before it's completely flooded with the typical mass produced garbage.
I hate to be a cynic, I really do, but the site already shows signs of low quality submissions. Case in point:
