We've considered both of those issues. People will not use your app until there are some offers in their area and businesses will not make offers until. We're working on building a userbase before launch in numerous ways. Traditional press, word of mouth, some other things. As for businesses making offers, we have a strong sales team with existing relationships with our target businesses. why would a business make an offer to people who are already IN their store? We are not targeting people who are already in the bar/restaurant. The idea is to drive people there who wouldn't go otherwise. We will check you in using foursquare api if you have a foursquare account, but you must check in with us/be registered with us. If you're say a foursquare user at the bar who checked in and happened to be there, no dice for you...because as you said, why would a business give an offer to people already there.
