(3) Facebook does not run nuclear reactors or bank systems. There is a high incentive to switch from buggy bank systems. There is little incentive to switch from buggy social network websites.

I'm arguing that facebook wants to run something even more important than a banking system. For example, Facebook wants me to share posts that are only visible to me. Such a post could contain secrets that could have huge consequences on my life and life of others' if they became public. It is pretty clear from facebook's history that each year, they want you to share more of such private data.

They started with you being able to share your drunk party pics. They are headed towards actually becoming something like PayPal. Really, facebook should behave more like a bank than just-another-social-network if it wants its users remain confident. In this respect, looking at their past success to as proof that all is well is a mistake because I am certain facebook intends to be much more than what it is five years from now.
