The style in these is atrocious. Useless commented out code all over the place, typos everywhere ("fede" for "feed", "depdencenies" for "dependencies"), etc.
Well, that's interesting if Facebook server fails to deliver you the javascript API files, Color.com will only display you an empty page. Their application initial load depends at a 100% on an external website on which they have no control. If facebook has a downtime for that file, nobody can load their application. That's sounds like an awful idea.
On the bright side, all the JS is not obfuscated, and is quite an interesting read:
