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

I see there are hash-tag such as:

#SciFiFridays
#SciFiSaturdays
#SciFiSundays

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.

#SciFi

@reiver They perhaps use #sff or #writingcommunity or #writing

@dilmandila @reiver I find some under the writing community tag, but the real way I see that sort of thing is to find SF writers and then to follow them.

Hashtags get used much more sparingly here than on a platform like IG. Many (myself included) simply ignore a post if there's a big hashtag salad at the end.
