Fair point. I still feel the same way, but I understand about FB is that friends and family are hard to leave behind and its hard to corral people into a new platform, when most people don't see social media as that important to begin with. It's like people are stuck in this hole of apathy. It's also a free service, so most people don't give shit. So they don't leave then the person who does care doesn't leave because all their apathetic friends haven't left and so on...

As for Airbnb, because money is involved and its a retail transaction the game changes. It's like in Freakonomics how once you introduce money into a relationship, a whole new set of dynamics emerge.

Think about your affinity for retailers. Do you really care if your Moleskin notebook was bought from Amazon, Target, or B&N? You probably just went with the cheapest.

It's not similar to Facebook at all, Craigslist would be a more apt comparison.

That is a better analogy, seeing as it's a direct Craigslist competitor (Craigslist has offered a similar short term rental listing for a very long time)
