[OSM-dev] [bug] direction of GPS traces

  Everybody can download GPS points for an area, which will include your 
  points, but when they do so they (a) have no idea which user uploaded 
  those points and (b) don't get any timestamp information for the points 
  at all. In addition your points will be mixed up with those of anybody 
  else that has uploaded traces in that area (whether public or not).

In sparsely-traveled areas the set of points has almost as much
information as the ordered trace.  I can see the value, though, so
perhaps private traces should just be labeled as semi-private or
semi-public.
