I would love to see this as well, seeing as how Microblogs prosper! Please, add your ticket to https://github.com/MbinOrg/mbin/issues - it’s a recent fork of Kbin that’s governed by a community.
Also, account for possible scope creep and try finding a solution in what Mbin already has to provide with extra steps. For example, test whether the video you post on PeerTube with one of the tags featured on a magazine does actually appear on Mbin. It most likely does not… unless you try following the PT account from Mbin? Do media previews work on these posts? We could really use some help understanding this model and possibly make a fun multimedia experience that would outgrow plain text.
What about “We Fedicast”?
