I agree with this, but not to the extent that we should kill it altogether.
Less focus upon it would be nice, however much of the userbase is all for Gaia.

A more defined sectioning of the forums would work better, e.g. put things that are alike in groups, such as Gaia, Neopets, etc together, and WoW, Diablo, etc. (MMOs) in another group, and so on from that.
From my own personal experience, after a while you grow from things such as Gaia onto more in depth games such as World of Warcraft and the like.
