Which of those are not “advertising” of one sort or another? Twitter was a dumb idea to start and I still just don’t see any appeal.

Insta was photo-based FB Lite.

Fark>Slashdot>Digg>Reddit>Lemmy was/is about community and sharing of ideas and thoughts. Each had its own strengths and weaknesses, but the anonymity gave everyone an equal opportunity to participate.

The early days of Twitter seemed to be 10,000 people yelling in a room and nobody listening. Then celebrities took over and companies followed. Enshittifying it early on in the process.
