It’s not the same category of social media though.
You’ve got (sorted by best to worst)
- content sharing/streaming (Youtube, Netflix, Spotify, Soundcloud)
- “private” messengers (WhatsApp, Signal, FB Messenger)
- public messengers (Discord, Matrix, Telegram)
- forums (Reddit, Stackoverflow, Lemmy)
- microblogs (BlueSky, Twitter, Mastodon)
- personality cult (Instagram, Facebook, Linkedin)
- infinite scroll (Tiktok, IG reels)
- etc.
Each of these can be called social media, but they serve different purposes and some are more harmful than others
5 hours tiktok scrolling is an addiction
