I still don't know how to use mastodon, I feel like I'm only here to share my stuff and read replies, and less so any kind of discovery of following and engaging with other people's stuff

it seems like there's only a chronological feed of those you follow (which I usually don't like because it skews to the most active people), and a generic feed for your instance (pretty much useless), but no algorithmic discovery thing?

@acegikmo There is also a possibility of hashtags based content discovery, but only on a fully public posts. It has limitations, but sometimes works reasonably well. For example, it's possible to subscribe to hashtags, making it nice for following less frequent topics.
@autiomaa do people actually hashtag posts actively though? and are the hashtag listings algorithmic or chronological?
@acegikmo Chronological, but I think some of the ActivityPub client apps do algorithmic sorting locally.

@acegikmo I found your post because @NCarter mentioned the hashtags (#)gamedev and (#)godotengine (making them invalid here because they are not applicable here).

Whenever I see a post I somewhat like I follow that account. if they later don't post interesting things an unfollow is easy.

@acegikmo @autiomaa The short answer to this is that yes, people do actively tag their posts and searching / following tags is the way to go to get started meeting cool people.
@acegikmo @autiomaa I definitely try to hashtag things that feel like they have a definite topic (or at least hashtag the first post in a chain).
I think hashtagging is really the discoverability thing on Fediverse. (and I do follow the hashtags I care about)
