I haven't seen the same lower levels of posting and engagement that you have, but then again, my circle is small, really. What I can share, personally, is that I've also been incredibly busy and trying to keep up has been difficult! I'm behind on everything. E.v.e.r.y.t.h.i.n.g. I'm barely able to keep a Discord presence other than to say 'hi.' So, maybe, people are just suffering the "Holy-shit-its-Feb-2020-and-I-still-haven't-done-shits" and are finally getting around to having a life! AHAHA.
Or maybe they're just leaving a bigger reward pool for the rest of us.
I like the last consideration... hahahaha!!!
Although, this one seems legit too...
LOL!
