Regarding private toots, if you intend to keep them private be sure to check the new "Authorized followers" page in settings, which will let you see which servers of your followers will receive your toots.
@Gargron Great move! I'd suggest ditching the lock icon as well, for the same reasons.
(Sorry if this is already done, my local instance hasn't updated yet.)
@Gargron Makes sense. However, since they control their network they can make stronger privacy promises than you can. It's not the same thing.
Just think about it. 😄
