It's been interesting comparing Twitter and Mastodon. One of the big differences I notice is that the ratio of mockery to substantive replies is much lower on Mastodon. So if you're going to use both, maybe Mastodon is the place to try out novel ideas first.
@paulg kinda baffled Twitter has never tried concentric staged-release of tweets, from most-trusted correspondents gradually out to public - either on a pausable/cancellable schedule, or by prompted approval.
it'd work to both help authors to test/polish posts in safety – especially wrt inadvertent errors or confusing wording sympathetic readers could flag 1st – *and* as potential revenue model for Twitter & posters. eg: unpaid followers just get things 1h to 1d later.
