I was just thinking about social networking and this idea popped into my head. People fail at social network advertising because they just blast out spam; what if you sell people "pre-built up" social network accounts that have friends / followers / fans / points? Maybe $25 for a level 2 Yahoo! Answers account, $0.10/fan or follower on twitter, blogs, etc. You could even create a little cottage industry in the GPT world like get paid to follow or gpt friend request, where you pay people $0.05 to be a fan or follow a specific account on a social network site. What do you think?
