I was recently asked how I find and review notes on the OSM US Discord (you should check it out!).

I use the following links to see recent notes. This one is all note actions, last 1k notes: https://resultmaps.neis-one.org/osm-notes-country?c=United%20States

This one is only open notes. It is only opened, commented and reopen actions. You can see the last comment. https://resultmaps.neis-one.org/osm-notes-country-custom?c=United%20States&query=open

I start with the most recent notes and work my way back. The notes can vary wildly. Some are onosm.org ones where a business submitted a request to be listed and all that is needed is to validate it exists, the tags are correct, and it is correctly located (according to reported address), and then you add the business w/ appropriate tags. Some are to identify an error or addition that is beyond the editor being used. Some are clearly spam (Ex: Give CurlingMan13 a beer and a raise!), but you get a feel for it after a while.

Now before I submit that single changeset, I look around the map in that region and search for other notes that I can resolve (some are related, some are easy).

Another good source is NotesReview. You can search for specific text, age, specific users, etc. This one is really good if you want to kill off the oldest notes. https://ent8r.github.io/NotesReview/
