Usenet (and still there), mailing lists (hooray for any that use schleuder), a bit of IRC (though I was never one for quick fire & forget statements, today I’m good with Signal/Molly/Gurk and XMPP; Matrix never appealed to me), lot’s of Forums (mostly related to my favourite games at the times), some twitter (though I was never really comfortable with the hustle to gain more visibility through large follower numbers), switched over to identi.ca (and eventually many different ActivityPub servers, currently one Akkoma and one Lemmy; not interested in PixelFed, though it helps I dislike the dev’s attitude; PeerTube could be interesting as a consumer, but the UX still feels atrocious; I tend to leave my name/handle behind when switching, I’ll inform some people important to me, but I am quite happy not having to maintain friendships and a reputation, gotta do that in meatspace, and I find it taxing even there). Lurked 4chan a couple years, but was never comfortable engaging, too much “fake” being a horrible person. Was relatively active on reddit, but ever since the redesign I felt it was too cumbersome to use (yes, old., I know, but who wants to rely on a legacy version being available?), plus their corporate decisions were pissing me off more and more (Yeah, I’m a pretty stout software freedom person, down to using libreboot & canoeboot, though I no longer wish to associate myself with the FSF, given their tone-deaf handling of the whole RMS situation), so, yeah, eventually lemmy. I’m more quiet than I used to be, getting older, I suppose, but I was also never that into anything “social” in the first place (I’m an Aspie, who’d have thunk?), so I mostly lurk and only post when I feel I can actually contribute something meaningful.
