>but I’m going to guess Bluesky will be the same

I disagree. Bluesky will grow further and then be like a "Coke or Pepsi" to Twitter. (Albeit, it will stay smaller than Twitter.)

I have 2 threads accounts and never created a single one. That's because I had 2 Instagram accounts.

The difference is people chose to go to Bluesky, Threads accounts were just added on to your Insta account by Meta.
