Looks awesome. There's so much potential in better vim websites - vim.org is the old standby, but imagine - sharing colors, little tricks, gif demos, etc. Now just to get free time to implement...
Man, if you want to make a colorscheme sharing site, I'd love you. bytefluent.com/vivify/ is decent for creation, and http://code.google.com/p/vimcolorschemetest/ is good for seeing a staticish list of existing options, but a well-made site for sharing, finding, and discussing them would be pretty damn cool. :)
