I wonder how you'd do an imageboard-style interface on the fediverse. I first thought you could just use mastodon, but emphasize the use of hashtags as topics; however, that doesn't match up with how people use hashtags and also doesn't allow for proper moderation.

so i think each board would be a group. it doesn't lend itself immediately to shared groups across instances though. like, you'd have a technology@server.x and technology@server.y and technology@server.z, etc. because they're all created in ignorance or defiance of the others...
