That doesn't mean that we couldn't monetize them. As amouseinmyhouse said:Your value add model is an interesting one and it's worked successfully in games for quite some time. The basic gist to the video game version is to open the platform as a simple, but complete, space where you gain access to more functionality through time. You can bypass the time restrictions through money. Take Team Fortress 2 for example. All of the weapons in the game that have effect on actual game play can be unlocked through actual game play, or you can spend a few bucks and buy the weapons now. Such a system could easily apply to hubski where you earn gold tokens through the slow acclimation of social capital, or you can buy them in bulk with bit capital. This is one of the more interesting systems for me, but creating such a system would take a lot of time and consideration.
