It seems that some people thought they were private in a sense of only
being visible to oneself. If you use JOSM or Merkaartor then you have
the choice of simply not uploading, but if you want your traces visible
in Potlatch then you *have* to upload.

The full GPX trace (if public) will not only tell people who has been
where, but also link that to any tags you have given, and it will also
give access to any waypoints you may have set and tell us when exactly
you have been somewhere and how fast you were traveling, and maybe even
how good your satellite reception was at that point and what make of GPS
you were using. - While it is true that, depending on the density of
other tracks in the area, individual GPS points could be traced back to
a specific author even if not marked public, the amount of data that can
be gathered is drastically smaller than with a trace marked public, so
you should really not mix these up.
