Cash, cheque, credit or tweet?
When it comes to monetizing your social network we had a peek when Burger King offered whoppers in exchange for sacrificing facebook friends, but not much since.
In the case of "pay with a tweet" the larger your network the greater the value, and hence the more expensive things you can use it to pay for. Time to rethink those friend requests from old classmates perhaps.
PSFK takes this monetization of social networks further with the concept of social scoring:
