In perhaps one of the most interesting lures for Facebook users to become fans of a brand or product, luxury sportscar maker Porsche is celebrating the one million fan milestone by declaring that it will engrave all one million names onto a Porsche vehicle.
The vehicle will be on display at a museum in Germany. It's an original campaign, and surprisingly bold for just the one million mark, considering competitor BMW is nearing four million fans without any such incentives.
Speaking of incentives, are they okay? It's never really been discussed, but luring Facebook fans through bribery should raise ethical concerns with policymakers and regulators - although it's doubtful that Facebook pays any attention to the matter.
