Looking at what they are doing I'd say the information being dug out will be of value to the OSM community and help us understand a little more about the people who add value to the maps. It might even help us on the retention rate and bring the experience of the average mapper up a little. It's also being done fairly professionally and running something like this properly costs money, at least its not OSM money.
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. He didn't get that many responses from the OSM-talk message. OSM-talk is bias in that we don't have that many average mappers here, the national OSM mailing lists have more so it makes sense to make the request to a larger audience. OSM is difficult in that it crosses so many cultural boundaries but in this case I think the cross posting was reasonable to obtain the desired number of respondents. How would you suggest he obtained a large enough random sample?
