“If we dropped share-alike, nothing would stop players like Google or Apple from mixing OpenStreetMap data extensively into their mobile maps. And this is a good thing.”

No, this would not be a good thing. The OSM was never made with the intention to form a data source, that non-open services can use to improve their walled-garden-systems. If someone wants to use free data to create something, he can at least be bothered with keeping the derived data free. A problem, for which I can not see an answer is, that the OSM uses sources, that require SA. This applies for many Open Government Data, that have improved the content significantly. Abandoning SA would not only work against the idea of open data, it would also damage the map.

Zlitan seems to be covered in a usable state, but we should try to coordinate, as there are still some nearly white areas in the map. I thin the map is usable in its curent state in the areas near the coastline and in the city of Zlitan. The area west of Zlitan needs further work, Google says, that there is a village called Al Jum'ah 10 kilometers southwest of Zlitan. We don't cover this village and most of the outskirts of Zlitan between the City Center and Al Jum'ah.

I think it would be a good idea to mention this issue on the mailing list.
