I assume you mean this: https://www.msn.com/en-us/news/technology/jack-dorsey-backed-decentralized-social-network-bluesky-gets-30-000-signups-in-48-hours/ar-AA13cy21

30K people signed up to the waitlist (including me), because of course they did because Twitter has a huge reach.

But will those users actually stay? That's the difference between Mastodon and Soapbox. Mastodon has like 4 million dead accounts. Soapbox has active communities that stick around.

I have no doubt Bluesky will attract millions of people to sign up, but making it stick is harder.
