Simon, et al, mon cheris, dostlarım, meine Freunde, мои друзья,

The bias of over-participation by any particular group can potentially
be controlled since the survey specifically asks if participants are
employed by an organization that performs organized mapping (as an
employee of the U.S. Department of State, I had to answer that question,
"yes", since the Humanitarian Information Unit organizes map-a-thons,
even if I do not engage in it myself).  The statistics generated by the
survey can be normalized to reflect the population as a whole if the DWG
has a sense of what proportion of the OSM mapping population consists of
organized mappers and paid mappers.

As for the bias of including only English speakers, as a U.S. diplomat
who has functioned in the multilingual world of diplomacy for 30+ years,
the easiest workaround for us when we survey our local workforce is to
sit a non-English speaker in front of the computer with a fluent speaker
of English plus the non-English speaker's language nearby and have at
it.  It works pretty well for our opinion surveys ("Is Ambassador
Mustard a) bad b) rotten c) horrible d) dysfunctional e) terrible" :-),
semantic concerns notwithstanding.  I suspect a fair number of the
mappers out there who don't know English fluently have a friend who
does, and could take the survey with a little locally available help.
