Brent Simmons is done with Twitter:
Twitter was always a 51-49 thing for me — barely worth it. The company has not dealt with harassment. It has treated its third-party developers shabbily. And, at best, it was just quips and outrages — a diet of candy.
And then it was part of the system that helped elect a fascist President. This tipped it over for me: it’s no longer worth my participation. The shitheads can have it.
Can't say I blame him—his logic is beyond sound.
