Mastodon

They do have a "Don't show this again" button, so at most this will enrage the people it does enrage only once.

Eugen seems pretty savvy about making a quality product that works well out of the box. Mostly when things fail on Mastodon it's because the goals for the feature were different that what a lot of new users coming over from Twitter assume they would be. (And sometimes those goals were good and sometimes they were kind of nonsensical, like the by-design feature of not being able to quote-post.)
