Yeah. I know zero people from HN or, say, Reddit, and even from the tech/coding world (and past workplaces; not that they were a Signal weilding crowd even by a stretch). I have friends I can count on the fingers of one hand, at most both hands. I will never have to reach for the toes :) So if that's the opposite for you, then it might be the case. Or, honestly, even if that's not the case, it might be so. And since I don't have empirical research other than what I see "around me," I can't just say that's how it is "generally," even though that's exactly what I see :D

(PS. There was a time when WhatsApp ended up having really bad press a few years ago and I was abl to make almost 30-40 of my contacts to Signal but Sigal being Signal and its team/leadership successfully pushed them all away, a lot were crashes and what not. Even I was frustrated. It was the first time I was "using" Signal beyond "trying" it which is like an annual or half-yearly ritual now)
