I wish we had something like "communities" here on mastodon.
We do have this in the #fedi, no need specifically for #mastodon to have it @futurebird.
To begin with, have a look at this profile and you'll see that we have role play profiles.
Also #friendica does offer #communityPages for the fedi, you can join them and you can post onto their walls so the post's get redistributed to all the followers of that page.
If you have an idea or need for a specific community #rolePlay page, just send a request to this profile or @admin, this server is specifically dedicated to community pages/profiles.
If you want an entire role play server, we can talk about that too.
Actually the "Stammtisch" is around since 2019.12 and right now in refurbishing mode.
Just like two days ago we discussed this in spanisch with @mina, and got stuck, or are still awaiting the decision, for the name of the page, considering that it should be language specific. The names considered were teleteatro -> @fediTeatro, telenovella -> @fediNovella, @fediBochinche.
We actually do have even audioserver (podcast) too, so we could create much more once the texts are established. And of course mastodon profiles can post audio snippets up to a certain size.
Always remember, the #fediVerse is a #doOcracy not a #cheerOcracy, a #claimOcracy or a #envyOcracy.
btw
It is utterly wrong to expect one platform, in this case mastodon, to do everything and offer everything. That's the centralized wallet garden setup and thinking we were taught. The strength of the fediverse and the #activityPub idea is decentralization, not only in instances but also in platforms and what each and every on brings to the table so we can feast together ..
