I think that's good self care, to take a break from posting. Announcing it goes both ways: either don't and then ppl begin asking why you aren't posting, or announce you're cutting back and ppl ask what's going on!
It happens with me too. I guess we could change our smiley icon under our avatar... or change the phrase saying "Taking a break from posting" ????

Any which ways works!
Holidays will be over soon... and PC will adjust back to normal, whatever that is.
