I’ll start:
- RSS and blogs, news vs. social media
- XMPP vs. WhatsApp/FB messenger/Snapchat
- IRC vs. Matrix, Teams, Discord etc.
- Forums vs. Social media, Reddit, Lemmy(?)
That’s what I used twitter for tbh. Since everyone is on it it’s easy to follow people, get instant updates and maybe even discover something new through the people you follow and their likes. It’s really a shame it went to shit, it was the lurkers perfect tool, especially when it comes to artists or content creators.
Not everyone is on twitter, but lots (all?) of Content Management Systems and blogs have a RSS feed.
As an academic, I’m syndicated to several labs and research groups which have their own websites, but don’t care about being visible on Twitter.
