But I feel that with Twitter becoming a private company owned by a single controversial person, Twitter lost a lot of its appeal.
It could be very unfortunate (if Twitter just goes down the drain without a replacement) or it could be the start of something new, if a new way to interact comes up.
If the community moves to another form of communication, I hope it will be something decentralized that can not be taken away from us again.
That is the reason why I am not enthusiastic about Mastodon. Mastodon is not decentralized. Unless you run your own instance, you do not own your social graph.
