irc is the only place i can reliably actually talk online, and discord to a lesser extent - on tumblr i just reblog stuff and everywhere else i lurk silently at least 90% of the time
every time i join something new i go "i'm not going to just lurk forever THIS time" and then i do anyway, and the longer i've been lurking on a given platform the harder it gets to delurk
for some reason i found it a lot easier to post on oulipo but i still didn't post that much there either
