No, not necessarily. Mastodon is actually "social media", as opposed to twitter/X, bluewhatever, facebook, or any other commercial outlet, to be honest, all of these have become "feeds" of promoted content designed to maximize "engagement".
Mastodon is social: you follow people, you see their stuff. It's what social media used to be.
Bluesky is really lagging in user adoption because the name itself implies some sort of political divide, and from experience, it seems that it's an echo chamber where "right" activists are getting demolished at the first occasion, I wished it would have a mix of people and opinion.
no one really knows, when broadcasters started using party colors it was all over the place and they settled on blue for dems. i guess its because neither party was socialist so there was no association with red like in europe.
You’re posting that on HN. I consider HN to be social media but lacking the most pernicious features (ads, algorithmic feeds) and benefitting from both strong moderation and self-policing. But it gets to do that by being funded from extrinsic sources, which is itself a compromise.
