I'm sure there's at least one technical person high enough there who is aware of how inefficient their implementation is, and how much better it can be. And I suspect that person is unable to do anything about it, despite being in a way better position than anyone on the outside.

But ... the real question, is even if I brought it in a turn-key and backward compatible setup for them (that is, they pay $3M, I install stuff, we flick a switch, and everything just works) - would it be worth $3M to them?

I suspect the answer is: Not worth any kind of risk or hassle to save $10M/year (or however much it would save them; if it is more than $10M/year, I'd be surprised).

I don't know how they spend their money, but I'm willing to bet that running the service is less than 10% of their expenses. (Of the money spent to get e.g. win95, or a new drug, to market, r&d costs are usually no more than 5-10%)

I think Twitter hasn't been a lean organization in years, and they took too much money to "reboot" themselves as a lean.

I think Twitter is already dead, it just won't acknowledge.
