One of the huge reasons twitter will always have a loyal user base is because of all the celebrity personalities. This leads me to two more questions:
Who are some interesting people to follow on Mastodon that already have some good content?
Are there any "celebrities" or well known persons using Mastodon?
That's sort of a chicken or the egg problem. Like people that are instagram famous just sorta pop up. That will probably happen here@cbri
