Yes, that’s a good point that sharing the plus code on its own is a way for the recipient to pick. It would be great if the “geo” schema handled plus codes (or plus codes had their own schema for click-ability!)

The “share” links from a specific map tool are good for just copy/paste links, though take up a lot of room in a paragraph, hence why I was looking for something more concise. Using just lat/lng points has the issue of implying an infinitely small point rather than an area, even with levels of precision (https://xkcd.com/2170/), which is why I was looking at other coordinate systems that gear toward areas than points.

Oh, I know why I did that now; the in-browser editor iD has “public” as an “access” option in the drop-down, but not “yes”. Should probably either update the editor or the wiki page about the access tag…

Oh yeah, you’re right!

It also made me note that those hidden playgrounds are the ones with grass overrunning the sandbox, and other equipment in dire need of repair. If there are playgrounds that are unnamed and unmapped, I bet they get passed over for funding and maintenance as well, which is another good reason to get them mapped!
