It's all opinions, but I think Gaia would benefit more from the opposite- like any avatar/MMO site, I'd rather see more than less without having to dig around for that information. See what the avatars really look like, what features there are, etc. If all I see is full manga body shots, but no true idea what's up, that turns me away from some sites.
While the current page is a little out of date, it is still appreciated for doing just what it needs to. "These are our avatars, these are some of our major features, feel like joining?" It lets someone passing by know what to expect in short order.
