I personally just haven't been on Steemit for a couple of months after a car accident and an unrelated death in the family, so I haven't been reading and voting. I've noticed the same trend in the few posts I have done, though, and wondered the same things. Is the community shrinking? I dunno.
Stay tuned until the end of March at least, because if our next grant comes through, we'll be soliciting short stories for an SF anthology, and paying above-market rates.
Not that it matters short-term, but Greensboro Science Cafe is using our Earth Day session to examine a couple of carbon dividend proposals. https://www.facebook.com/events/1845262262413229/
I'd love to see some stories around those proposals, and will devote next month's IGMS column to the issue. I've never really referenced any Steemit stories (by any author) with those columns, which now seems like an oversight.
I'm sorry to hear about those tragedies in your life. :/
