I appreciate that it is leaps and bounds more friendly to the new user, and that it doesn't come off as a drastic wall of text (that set off me when I first visited almost six and a half years ago).
Improvements: Toss in more avatars! As of right now, it feels a world apart from Gaia, with three stalwart avatars at the entrance; peppering in random items or different outfits (or even just a few cropped heads) will make it feel more like it is part of Gaia and this would definitely make it more hospitable to a new user.

I like it. Thank you, Gaia! Maybe actually put it on gaiaonline.com rather than an external host, though? How is this s3.parature.com getting our usernames and avatars?
Its externally hosted for the time being so the developers and UI artists can display it in its current state without opening a gaping hole in the security of the development servers. This is known as being "intelligently secure", as they are sharing (a portion of) the contents of the development servers without leaving the door open.
This is just for the time being, until it unveiled next month.
