http://demyx.com - new theme need criticisms

i've been working on a new theme for the past few months, it's highly based off of the new myspace layout. like the new myspace layout, my site scrolls to the right instead of going down. i'd like your criticism on how i can improve. as far as page specific js, should i cache them or just leave it the way it is? for example

elgg_register_simplecache_view
