Personally, I think it's way too busy.
There are way to many things to click on IMHO.
There is: News Headlines, Developer's Planet, Documentation Update, Forums, Special Events, Haiku Operating System, Developer Resource AND Dev Community. Couldn't we combine these two with Developer's Planet?
There is also: About, News, Development, and Community at the (almost) top and Contact Download and Report a Bug on the right after a bunch of white space.
Also, would the masthead/logo area be clickable ?
I don't know which one to click first.
I'm a fan of traditional, simple design. Can't we just have maybe 7 or so categories across the top or on the left hand side ?
It seems to me to be too much information.
