I believe that the AMA topics are a sign that people are beginning to both establish and recognize other members and the persona that they have built over time. An AMA is also a way to further build that persona for those who might be curious or interested in the person behind the avatar. As far as being amazed (and probably amused) at what people post on a video game forum, this tag sorts of #offtopic items and that means just about anything (within reasonable limits). The forums here on Bungie.Net have never really been a "video game forum", sure there were forums (and now tags) that are dedicated to specific games and even gaming in general, but since it first came online, this site has been (and continues to be IMO) a "fan community" site where our hosts have understood that fans of their company, fans of the games, and people who just fit a particular personality and mindset would benefit from a place where they can come and socialize. #offtopic more so than other tags.
