I feel like Foursquare had their biggest revenue thunder stolen by the hype around the Coupon companies. They had a major opportunity to be a universal customer rewards program, using checkins as a proxy. But that has to be a much tougher row to hoe after the rise and fall of Groupon et al, and the stories of burned businesses in their wake. I also think they missed the boat a bit on social. They had a chance to focus on building communities of people with geographically similar habits, but I don't think they ever found the way to make it click. I don't know what the revenue model would have been there, necessarily, but it does feel like they missed an opportunity with it.
