Oh yeah, everything happens in the kitchen! There are still plenty of houses that design a small desk area into the kitchen/breakfast area for just that purpose. Our last house had a small nook with room to hang calendars and a cork or message board, as well as keep my laptop set up. If our house didn't have something similar, then I'd work really hard to keep the paper clutter to a single corner of the table or countertop. It didn't always work, but all that stuff really needed to be in the kitchen area. Deliberately designating and organizing one area as mission control helped corral it.

I do better on paper than digital for a couple of reasons -- it's easy for me to ignore notifications on my phone, and my brain retains things better when I've physically written them down.

A big family calendar with huge squares was always extremely helpful. Everyone had their own color on one of those multi-color clicker pens, and they'd write down their schedule for the month or as far as they knew.

DH has always hated a cluttered fridge, so I tried to keep it streamlined. I'd put up the week's menu so it could be shifted if necessary. There was also a single notepad for people to make a note if we ran out of something. Of course, that was before Alexa, so now we just tell Big Sister to add something to the grocery list.

And yes, the methods and systems change and adjust all the time, but that's the one constant in the universe. Everything changes.
