I have yet to see anything so groundbreaking in JS that it would actually warrant obfuscation. But well, I guess that if you're obsessed with the thought of script kiddies stealing your precious c0dez, then JS obfuscation might be for you; the market niche indeed exists. I'll be curious to see how this compares to the existing obfuscation tools.
I looked at the link page. The CSS was perfectly sensible (and available) and the JavaScript just looked like it had been run through something like Closure.
Perhaps they have yet to eat their own dog food?
Seeing as the service hasn't been implemented, and the development isn't finished, why would the page be using it?
