I like it and I see why a service like this would be helpful. But, is there enough incentive for your users to answer the texts?
For example, if I'm at a bar in NYC drinking with my friends and I get a text (from a stranger) asking how much a pitcher of Coors is, I'm likely to answer because it's a quick text back. But, if someone asks me to list what's on tap, I'm likely to ignore the message because it's a lot of work and the payoff seems very little.
Also, I would have been quicker to signup if I didn't have to use a third party.
Overall, I think it looks awesome.
