Hum, I was finally curious of what I would find there. I find this:
"It is important that OpenStreetMap keep the use of maps non-commercial."
Is this really a serious question, or a serious survey, or am I just
completly mistaking about OSM since the beginning, or is my English not
as good as I thought it was?
Sorry for the interruption,
JB.

In an ideal world the way to get a proper random sample would be to select
OSM mappers randomly then message them. Hopefully you'd get better than
90% response rate to keep it statistically meaningful.
Reality is you might be lucky to obtain a 2% response. So the next best
thing is OSM-talk and hopefully he'll get the 1,000 responses which he
needs to make it statistically meaningful.
Remember that we're sending emails and that the task can be automated,
so a 2% response rate isn't really an issue. And it's much better to
individually contact a uniformly random sample than to globally
contact a biased sample (only a particular kind of contributor follows
mailing lists). As a added bonus of contacting individually, you
already know the person's mapping profile.
Here are a few proposed guidelines to keep things in check though :
* treat a survey like an import: it should be community-reviewed and
accepted before going ahead. Be transparent, be usefull, be well
writen, be multilingual, etc.
* set target request and response counts ahead of time, and stop
sending requests whenever one of the counts is reached
* provide a way to opt-out any future survey via you osm account
Any other do's and don't ?
