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(?)
  • Agree on RSS.

    Don’t have enough experience with XMPP.

    IRC is not a secure protocol, I think matrix takes the cake there. (although I really miss IRC)

    Lemmy and Reddit do have an upvote feature and aggregation across different topics / communites, which I think it’s what old school forums lacked.
