Something like this exists for peertube already, I didn’t look at their code but one might be able to fork it to work with other platforms.
This article feels so generic. Where’s the info about instances (except briefly mention it, and not even directly)? Where the info about ActivityHub and the ability of using different platforms in the fediverse (even if it’s not full compatible with each other) from your account at a specific platform in the fediverse? It’s just missing key features that should be introduced when presenting the goodness of the fediverse.
I’m still glad Fedi gets more attention tho.
I just don’t think that new msging app will have a larger userbase than matrix. I hope I’m wrong tho
