Now that i've used it for a few days, it seems Just Obvious that medium to large organisations/corporations/institutes should have their own Mastodon server. If you want to toot as the spokespersons for %FUNDER% or whatever, the most natural authenticity is to toot _from that domain_.
@drj11 from a data ownership and identity perspective it makes a lot of sense. I would expect governments and political parties etc could use this effectively.
