Honest postmortem of a "sharing economy" startup: "People do not want to share."

Doesn't hold back any punches:

For the rest of the “sharing economy,” it is going to take more than building a platform and expecting people to share. Here’s a sad fact: Most people do not want to share. They want convenience. They want to be elated. I challenge anyone working on a sharing economy startup to solve one real problem instead of nattering on about all the waste and underutilized resources that plague our society.

And yet still promotes Airbnb and renttherunway as solving real problems.

So which sharing companies does he not believe in?
