Notes are a core feature of the OpenStreetMap.org website. They enable to add a comment on the map to assist others in mapping/editing OpenStreetMap. Other users can respond to your notes, for example to ask for additional details if necessary.

Example of valid and useful note can be "a new road was constructed here" or "this shop is closed and not existing anymore".

Please do not use notes for general discussion or storing information not otherwise used in OpenStreetMap.

This note makes *no* sense in the OSM context and would be better shown on an https://umap.osm.ch/
