Twitter looks like a sunk-cost fallacy run amok. The pitch was that it would become ubiquitous, and it clearly isn't and doesn't seem like it ever will be, but the people who are most heavily invested in it act as if it was, presumably out of self-interest.
Now that I think about it. I wonder if those heavily invested think it as part of their job while it generates them hits of dopamine like drugs... So they can easily justify their addiction...
