No, I don’t think it will grow as big as the other socials. Because for the average Joe Normie it is way too complicated to understand what the fediverse is, and where they should sign up or post. In other words: the entry barrier is substantially higher than the competition.

However with simplified browsers like Wefwef it makes things a bit easier, and I do think it can grow reasonably big. Maybe in the future when there is more information available and the fediverse has matured.
