It will not in itself make me leave Quora.
But it adds to the things that make me think badly of Quora—along with the UX Russian Roulette, the Black Maria of moderation removing people in the middle of the night and the headscratchingly inexplicable decisions, the lack of a clear mission, yadda yadda yadda.
I will leave Quora, as I’ve answered before, when it stops being fun—or to be more precise, when it is unfun substantially more often than it is fun. Outage is frustrating; if I’m halfway through a response on a comment, intensely frustrating, as was the case a couple of days ago. So long as its impact is less than weekly, I’ll put up with it. But these things can have a drip drip drip, cumulative effect.
