@mdemeulder I hope you'll have a rewarding and satisfactory experience using mastodon (and other actipub services).
In ways, mastodon is more like a #listserv because no "algorithm" suggests what to see: one sees and is seen by other members of one's server. Also seen by any followers one has from any server. And (lastly) seen by anyone on a server/instance where someone follows you, if they (others) look at that view.
Post-lastly, search results, esp. with #hashtags.
