I disagree. When Twitter first started taking off at SXSW twenty years ago it had very little in common with Facebook. There wasn't an algorithm, there were no ads, and there was barely a website. You just received text messages from people you followed. You mostly interacted with it via your phone and for many of us, that meant text entry on the digits keys of a Nokia or Motorola phone. It was delightful. You likely personally knew all the people you were tweeting with.
Facebook was something you did on your computer. There were lots of ads and they had just launched the algorithmic news feed. It was the beginning of something bad IMHO.
