The only reason I'm following celebrities is to stroke their ego so that more of them come over here.

I'm not interested in replicating Twitter on Mastodon but I am interested in providing viable alternatives to corporations. In the case of #SocialNetworks, that necessarily means making the alternative as entertaining as the corporate stuff (as is reasonably possible), which necessarily includes getting celebrities on here.

P.S. One e-celeb (?) I watch on YouTube said that she tried the Mastodon mobile app but when she saw that she has to pick an instance, she immediately noped out.

She misunderstood instances as walled gardens. (Of course, that's true for some instances, but) I bring it up only to underscore that even signing up is a significant point of friction for the non-technically minded. These federated social networks have a ways to go before they can compete with corporate social networks.
