Some of our new users that joined last night already have close to 100 followers. They've been posting art with alt text (this is important as so many folk won't boost any media without alt text), using good hashtags (hashtags are really important for finding and following relevant content), interacting with people, following people, etc.

There are no algorithms on fedi, and what you get out of the community depends on what you put into it.

Make an effort.
