Interesting social commerce app on Facebook called “Second Porch” that does vacation rentals – lets you find people in your extended social network to rent a vacation home from – or to.  Keeps it in the social family so to speak. Forget crowdsourcing, “friendsourcing” takes the risk out of vacation rentals – you know the face behind the place.

If only Virgin Atlantic, Avis or Expedia took this idea and ran with it, selling their travel services on top – they’d have a sweet (and profitable) social commerce solution on their hands…
