Hi there,

see it as a kind of service I provide ;-P

As mentoined before I use OSM primally on my mobile via OSMAnd~, while exploring lonely to lost places.
I put additional nodes on buildings/structures/specific dangers of interest to provide more information for OSMAnd~Users via the "point of interest" function of the app.
Otherwise it wouldn't be possible to get this infos while navigating or exploring offline, because the offline dataset of OSM doesn't provide this level of detail for 'simple buildings' etc.. Keep in mind that in some areas I've mapped there isn't any cellular radio avialable - eg. in the Southern military facilities of Lastovo.
After all I can't see any disadvantage in this procedure. Let me know, if you find one.

Lastovo is 'my little baby' - it was poorely mapped when I firstly arrived there and there's still so much work to do...
I will continue - time after time - so feedback is welcome! :-)
