I talked to the guy who made the latest post (Joshua Dallman) and he said the comment system broke with a WordPress version upgrade.
It's not a get rich quick scheme. It's a guy who has over 20 years experience in the video game industry giving advice on how to be successful. In the post I linked to, it even explains that going out on your own to do this can take years, and he likens it to learning to play an instrument. You practice a lot on your own and it can take a few years to get good enough to produce anything good enough other people want to listen to (or pay for!).
Nothing quick about a few years before first real sales start to happen.
