Is there a way on lemmy to have small communities new post always come up on the top of your feed?

Choosing "all/new" gets the job done.

And many Lemmy clients have more options with additional cleverness to get a feed with a mix of fresh and familiar.

It's worth pointing out (to communities thinking about moving) that there's nothing algorithmically suppressing new content here.

Getting (and staying) noticed is way easier, here.

First of all this isnt reddit so its not subreddits. We are communities here

And second: feed sorters exist
