Editorials like this worry me because it means even more attention will be placed on GAF, and as a result more people will want to join. While I'm a relatively recent member, I joined this website because I lurked it for a six-month period and enjoyed reading the conversations here. It would be a shame if GAF became the "next big thing", because I think it would harm the website's overall quality.
I would also hope that game developers don't start to look to GAF for approval. While I like our poster base, game development should come out of inspiration, not focus group testing. GAF is a relatively intelligent body, but it would still be focus group testing.
