PG:You don’t know where people are going unless you expect them to tell you all the time. You have to find a subset of people who super-want to talk to one another. Enough to seek out and sign up for something they aren’t using. If I were you i’d stat over. You’ve spent 60 days on this. Plenty of companies start over after 60 days. The very best startups solve problems that founders themselves have. What is the worst problem in my life.
First idea that popped into my head: frequent fliers who like to sleep around and/or cheat on their spouses. If you're always on the go, away from home (for better or worse), an app connecting like-minded people easily might have a viable group of customers. Basically, a mobile/geo version of AdultFriendFinder.com. Want to share a hotel room to fool around in, and save some money by doubling up? Stranded out of town with nothing to do? Etc...
People will go out of their way for sex, including logging into an app and planning ahead. The question is, how big is the customer base, and what are they willing to pay? Do you end up with too many men and not enough women? Perhaps it's different between W4M, M4W, M4M, W4W.
