I know this is some boomer tier shit I'm on right now, but im not gonna download snap or discord just to keep chatting, if you're wanting to talk to me somewhere other than an app I'll just give you my number.
I get WHY people would prefer it, keeping a little bit of their info private, but im still not downloading snapchat.
Also this is in the context of ENM/poly stuff
I've only been actively poly for about a year, but yes, at least in my major US city. Im of the same mind as everyone you mentioned.
Might be a localized thing tbh, I'm also in a metro city and all the poly ppl I've met use discord, though I only know trans poly ppl and trans people tend towards discord anyways lol
It's not I'm old and polyam and generally date younger people and they all fucking use Snapchat and discord.
