I'm wondering what the business model is exactly.

Or rather what it will become once the VCs who are paying for all this start the squeeze.

I'd be nervous about getting in too deep with tools from a company with what looks to me like an utterly unsustainable business model. The house of card will have to come down, won't it? You don't want your stuff to go down with it.

IDK, been wrong before, could be here too. It's disconcerting, though.
