Riiiigggghhhttt - that's not exactly an interesting day out for most people. Of course, the worse a job you make of armchair mapping (and boy am I sick to the back teeth of cleaning up the mess left by armchair mappers) the more useful the ground survey. > The total amount of work involved is the > same, but by kick-starting from the OS data you get to the 90% mark faster, > even > though the final 10% takes time.

Great. An OSM database filled with only OS data is a) at very best, only as accurate as OS data and b) a massive disincentive to people to go out mapping. I really don't understand why you keep arguing against the sequence of a) send some mappers out then b) use OS as a check for the minority of mistakes. Doing it your way leads to vast areas with names filled out and nothing else. If I could find a way to stop you from damaging our community in this way, and damaging the long-term prospects for the OSM project, then I would.
