I think there's a conversation to be had about problems with gatekeepers in traditional publishing. It can be a hardship to meet literary agents or acquisitions editors. It requires expensive travel, expensive conferences, and networking that doesn't come naturally to introverts. Although you might hear that it's possible to get "discovered" in the "slush pile," actual examples of this are rare.
However, this guy who blogs about his rejections just comes across as a pretentious douchebag.
