When you think about it, there's really only a few things to go out and do. You can:
Go out to eat/drink (bars, restaurants, coffee shops)
Attend a show (movies, plays, concerts)
Play sports (basketball, fishing, hiking)
What else is there? Sure you can go to a NEW restaurant, see a NEW movie or play a NEW sport, but when is the last time a truly NEW category of activities arrived on the scene? Innovation in technology has made us more social and resourceful than we ever thought imaginable. With the arrival and mass adoption of powerful mobile devices, we can use this technology to make us more active in the real world.
While we're at it, lets take the freemium and advertising models we learned from the consumer internet and apply them to real world activities. Give us some incentive to break away from our TV's and computers with no obligations and I think we might just do it.
