text: I'm not sure how the number keeps rising when I see what I close daily of new incoming notes/spams, not to mention when I find a hundred or so a day on occasion which I've overlooked.
  Wonder if the feed I follow leaves things out more than I know of.

  For a good example of how to map and how to map by notes, check out
  https://www.openstreetmap.org/changeset/51630730#map=17/21.54317/-77.26192&layers=N
  Zoom in to see more, and out to see additional ones, as whatever limit the website puts on displayed number is exceeded in all but the most close-up views.
  I quickly left that area after resolving, I think but one.  Had better luck elsewhere.

  The unresolved notes issue can be a number of reasons.  The minority of mappers make use of notes so it's quite likely a local will resolve the issue with no awareness of the note.
  Then of course, maps.me comments added when editing the map for I-know-not-what-reason.  Too many of those.
  And a lot of people seem to be using notes as private bookmarks, marking again already-existing places to help them stand out.  Even with onosm.
  Or apps that post notes for no good reason when the editor deals with them elsewhere.

  I'll have to find your work and see if it matches a discussion in notes I vaguely remember.  Somehow I have the feeling the hiking trail needs to be mapped as a relation.

  Not sure about routing.  There could be many reasons; I suspected surface=clay for a bridge in one area.  I've never checked routing.  I always have done that by eyeball and bad habits are hard to break, particularly as I prefer to be in charge of how I walk somewhere that usually means finding an unmapped path.
  So no, I'm no good with routing and can't help there.
