"Incentivized social software.
Up until now, social sites have had to rely on non-monetary currencies such as likes, followers, karma, upvotes, etc. With Bitcoin we can add actual monetary incentives to the mix. This is happening organically on Reddit where users are tipping each other using Bitcoin and Dogecoin. A good exercise would be to go back and look at the history of failed social sites and try to rethink them using financial incentives."
