I’m not sure if people looking for something laid out like Twitter or other microblogging sites would necessarily move to Lemmy, which is more like a forum. The activities on any social media may be largely the same, but presentation matters a lot.
To me, Lemmy and other forum style SM is like going to a bar and finding people to have a conversation, where as Twitter/BlueSky/Mastodon/etc are like standing on a street corner and just yelling random thoughts.
