I'm interested, but...not really enough information on the site right now for a detailed critique. Is this going to be like the bastard love-child of Etsy and Groupon? How's it going to work?
It's really more along the lines of Kickstart than Groupon in that you put a "listing" out to the public that has an end date, and people commit to buying during that time.
I signed up, for what it's worth, and would interested in it as a buyer.
