Hello John,

I usually create a link at the OSM map in the Share section and then dig 
out from the link a latitude and a longitude for a place.

It is a very good idea to create an easy way to extract a latitude and 
longitude for a location on the OSM map say to clipboard in one click, 
and then vice versa, just drop two figures into the search box and get a 
marker on the map, - does not matter if these two figures separated by 
colon, space, etc. And make the same functionality on mobile version, in 
JOSM, apps, etc.

Latitude and longitude are physical values, they will never change for a 
house on Earth, no matter what. They do not depend on politics, 
economics, linguistics of the current moment.

Certainly, for most OSM mappers an address is not an issue, however we 
could take a part of responsibility and create an address system for 
billions of people who do not have it.


I was impressed when I read Article #70 [1] of the new constitution of 
the Canton of Vaud <https://en.wikipedia.org/wiki/Vaud> (my translation 
in English):

/Chapter 9 Associations and volunteers //
/

/Art. 70//
//1 The state and municipalities take into account the role of 
associations and recognize their importance.//
//2 They may grant to recognized associations support for their 
activities of general interest.//
//3 They may delegate them tasks within the framework of partnership 
contracts.//
//4 They facilitate volunteering and training for volunteers./


I mean an association like the OSM has got its importance and its share 
of responsibility, and it does not matter if it consists from volunteers.

Again great idea of yours, simple and elegant.
