http://www.usairwaysmag.com/articles/free_play/ Read it for yourself, need I say more? The dude's dead wrong, and all the good games got submitted on every site. there's many of the same features on many of the flash gaming sites as well.. I don't feel like correcting him.
I liked being called a coworker >.> He didn't really say much but at least it was positive. Games may be on other sites but AG does make its own great games/ helps others make them.
hmm...really this guy was probably dead honest about all the sites I am familiar with. Kongregate is the Youtube of flash games, while Newgrounds is the most established, and the first to pay people for flash products through contests, and Armor Games is the one with all the High-Quality games, some of which stay exclusive for a while before hitting the other sites. At least AG is getting recognized though, and with some positive feedback too.
