Started by 19 year old Jared Kim(profile), WeGame is a site where users can upload videos of their gameplay, and let other people comment on these videos.
He even managed to raise $500k(first round) and $3m in the second round of raising funds, which is quite amazing for a 19 year old !
I would never have gone for an idea like this, but as most innovative start-ups, you have totake the risk, and that is what Jared did, and well, congrats for him, for such an innovative idea.
