After almost 3 months of work, development reached version 1.0! Also I have changed its name from Taglocator to OpenPoiMap which is maybe more descriptive for the non-mapper.
And it is now available under its own domain name: http://openpoimap.org
Compared to the first version many improvements have taken place (thanks to the community) and it is fully described in a wiki.
The tool is handy for mappers, to check their own work and see what is missing from the map in the areas they know, but it is at least as useful for the layman mapuser who just wants to know the nearest Busstop, Bookstore, Library, Restaurant, Pub, Cinema, Hotel, Giftstore, Optician, Monumental Tree, Picnic, Windmill, Museum, Viewpoint, Parking, Bicycle rental. . . (not necessarily in that order!)
But if you want to check which Bar has no Telephone number, that's also possible!
Many improvements are yet to come, and development continues. Give it a try!
