Hey -- I designed this website, and made it with the super talented guys at Nilas. I was actually going to submit this tomorrow after I got a chance to put a page on the design process together! We built this in a little less than a week and a half total.
Don't miss the illustrations on the blog -- it was a blast to work on. Will post more process tidbits on dribbble in the next few days. (http://dribbble.com/sdw)
I'm in love with everything about this.
Dig the site. Call to action was a bit confusing. Read the blog essentially.
Very interesting idea though. Are you actually taking beta testers for the actual app yet?
