Sure, but realistically, it's not "just one app". It's the vast majority of Steem - that was my concern. Ned says it costs $2 million per year to sustain Steemit Inc's infrastructure. Whilst some of it is the frontend, it's implied much of it is running Steem API nodes - their primary focus now is to reduce costs on them. I don't have numbers, but judging by activity, witnesses will have to take up an order of magnitude or more greater load. At the current prices, all top witnesses combined well have witness revenues of under $750k. How will we support a $2 million infrastructure? Yes, witnesses can go for cheaper infrastructure than AWS, streamline things considerably etc., but the sustainability seems very questionable. Not to mention, Steem is tiny now. We'll need to scale 100x to be relevant to the mainstream, and 1000x to compete with Reddit.

It's not adding up.

Yes, the price may increase, and it likely will, but history has showed us that price does not scale with activity - it is its own speculative bubble, and not a sustainable revenue model.

To be clear - I'm all for witnesses co-operating for the betterment of Steem, but I'm concerned about the harsh realities of the situation. Is it even feasible?
