Do you use foursquare? They switched to osm.

The majority of foursquare users wont switch to OSM - the superusers
weblink is only a first though promising step.

No; GPS (like when you are in Syria) will still show you at least the
position of the entry of the bakery.

So the idea of leveraging OSM data through ressources like the
gamified app foursquare, still is a source of information I would'nt
ignore.

Yours, Stefan
