I quit Facebook when I concluded the cost of remaining (e.g., constant vigilance for unilateral changes in privacy settings) was greater than the benefit.
Twitter sure feels like that now. Demands tons of effort to read stuff someone else decided I should read just to reach occasional morsels of what I subscribed to? Fuck you pay me.
So in the last month of being a new Mastodon admin I've seen: (1) a popular instance wipe its entire database and (2) a popular instance's operator ragequit and take the server with them.
Definitely an education in mastodon failure modes!
My sense is that the decision to become a Mastodon admin comes with some responsibility to plan for continuity... the broader Mastodon community suffers when there is no plan or a lack of effort to carry it out.
