"Mark Zuckerberg might have a fit of brilliance and then announce a revolutionary ad platform that somehow actually works on social networks." I'm not sure it would be altogether brilliant for Facebook to improve their advertising to be action-oriented as opposed to passive. People use Facebook for events and will soon use it more for Q&A and eventually "what ___ should I buy?". I think it would be common sense at that point to have ads targeted to a user's planned action, just as in the past ads have been targeted to very specific demographics.
