I honestly think it sure will. People will probably go in 3 directions:
- Mastodon
- Wait for Bluesky
- Wait for Instagram “Threads”
Honestly, if people go fediverse way, they definitely should choose something like Misskey/Calckey. They’re much better options than mastodon IMO
I have seen posts on Tumblr from people who went (back) there because of the Twitter situation, so there is an additional direction.
