I wouldn't spend a lot of time reinventing anything to do with GPS traces.Why's that?For those of you in countries with NMAs that release things, or in urban areas where there's satellite imagery, maybe you can do without them. But in95% of the British land mass there is no other way of mapping.Personally I'd like to see _more_ emphasis on going out there with a GPS, and less on "oh, we'll find an import" or "oh, you can do it from satellite imagery". OSM as an agglomeration of imports is little more than one of those terrible "geodata catalogs" that seem to be discussed interminably onOSGeo mailing lists.
I think the reason for GPS Trace from the API being less important (rather than using a GPS in general) is because there will be so many of them that there will be too much noise in places, and the map will be nearing completion.
I do agree that people should be heading out on the ground to map rather than looking for import. It will be more likely that people will be using things like walking papers than a GPS Trace to do the mapping.
