Elitism is the new black? A karma whoring social network idea
So, I'm proposing the Mecca of elitist social networking sites. Any page created can be assigned karma thresholds for viewing, commenting, voting, whatever. To place a widget onto your page, you must meet its karma requirements. Want to view my new page? You must be this karmic to enter. Want to read my latest hack? That will cost you 1 point deposited to my account.
But those were not very good examples; there isn't any point in restricting your audience. But for abilities such as embedding pictures and video that can be abused, the karma requirements would be set very high by the karmic gods themselves (the top 100 users).
