Yep, I think the trick is here : thinking about using Facebook's Custom Audiences with @facebook.com addresses to get even more accurate targets.

I did the same a few years ago too with Adwords, but capitalizing on people's ego : to target "influencers" I wanted to invite for a startup party, I created special landing pages for each of them and bought their names as keywords on Google AdWords. They fortunately googled themselves (and if they didn't, I gave them a shout on Twitter). But now AdBlock attracts more people this strategy is a bit more complicated.

Maybe the right strategy for today is to do it Charles Saatchi-like : buy a billboard on times square saying "I want a job".
