[quote=afx114][quote=BGinRB]It is an unsustainable business model. The cost of infrastructure is enormous[/quote]

You are forgetting that infrastructure costs are lowering at an exponential rate (Moore’s law). Technology will improve a lot faster than the human race can consume it.[/quote]

That’s not what the Moore’s law says. Neither it applies in the original form since 2005.

Regardless, the improvements in processing power are offset by the advancement in services. Video will consume your bandwidth, facial recognition will consume your CPU, images taken with 10MP cameras will consume your storage space.
Your cost per unit of storage or CPU cycle will go down, but your cost per user will not.

You depend on display ads and push marketing to cover the cost. Businesses can’t use your product to increase productivity – you went straight from the early adopters to general population unwilling to spend $$…

I don’t know. I see the value for the user, I just don’t see a way to monetize.
