A paltry sum perhaps, but not unheard of.  Minimal executive paychecks have become fairly commonplace in Silicon Valley over the past decade or so; previous executives opting for the symbolic salary include Apple's Steve Jobs; Google's Eric Schmidt, Sergey Brin and Larry Page; Yahoo's Carol Bartz and Terry Semel; Cisco Systems' John Chambers; and Oracle's Larry Ellison, among others.

But perhaps Dorsey will soon be graduating to a new level, say a doubling of his salary to $2.80? It's quite possible that Dorsey and his board of director agreed upon the amount in late 2017, as the company was getting ready to transition from 140-character-capped tweets to its current 280-character limit.
