Funny, of all the recent YC companies I've been reading about lately, this one makes the most sense to me.
They provide a real service that lots of people (judging from these comments) seem to appreciate, which is easily monetizeable. In addition, I can see some great economies of scale here, including cheaper food due to mutually beneficial deals with restaurants.
Really? Because a company regarded extremely well by its peers and advisors, with a solid business model and clear plans for expansion, raises a seed round?
If you're going to say that when a company announces funding, at least provide some backup.
