Starting over here isn't as daunting as you might think.
To get where you were there, you had to battle bad actors and constantly fight algorithms that work to suppress you. That stuff doesn't happen here.
There's also a lot of baggage that comes with large accounts, and you're leaving all of that behind. For some folks, that can be a huge relief.
@kel I never understood the fascination with massive follower numbers... I was/am only 1700 or so, and I know I missed a lot because of how cluttered my feed got, usually by duplicates of the same general message/story.
