@freepeoplesfreepress @freemo @trinsec @khird After some months, my Mastodon experience is mainly on the timeline of people I follow or subscribed tags. I rarely use the "Local" section, because there are too much people and STEM subjects. So I think that Mastodon is not the right tool for creating focused communities, in case of large instances.
So the idea of @freemo can be pursued, but using other tools and approach respect a distinct Mastodon instance.
My 2cents.
