feature request: a way to fire into the void of a certain instance. say I want an art request, but no one on mastodon.art follows me, so I can't appear in their FTL, or I want to ask a BSD question, and just want to appear in a timeline on bsd.network. this lets you fire into specific voids, and maybe hope you get results.
maybe it'd work as a mention type? maybe a syntax such as @@mastodon.social would work.
@calvin an instance-wide inbox would be neat
