2017 - One Million Notes Added to OSM since 2013

The OSM.org Notes feature was released in OSM.org in 2013. It enabled users to add a comment on the map to assist others in mapping/editing OpenStreetMap. Other users can respond to these notes, for example to ask for additional details if necessary. Importantly, Notes enabled users to add information about the map, even if they didn’t know how to make the correct edit.  The feature allowed both registered users and the wider public to quickly indicate where there are errors or omissions in the OpenStreetMap data, accelerating the progress of the map.

On 25 May 2017, the millionth note was created since the introduction of the feature in 2013.
