Are there any Sci-Fi writers communities on the Fediverse already?

I see there are hash-tag such as:

But, I am not noticing people posting their own sci-fi stories or videos there.

Maybe they exists already, and I'm not looking at the right places.

UPDATE: #MicroFiction and #TootFic seem to be pretty active.

@reiver people here use #bookstodon to promote (other people's) books. (see also group: @ bookstodon )

I don't see authors using a specific hashtag when promoting their own books, other than a genre indicator like #romantasy
