Genomes Unzipped points me to a Nature survey on personal genomics for scientific researchers. With price points down to $200 or so many scientists have been at least genotyped. Though it varies by domain. Many molecular biologists seem intrigued by the novelty of personal genotyping services. In contrast, in a room of a dozen or so population geneticists and the like nearly half are liable to have already gone through some service.
All that being said, I haven’t heard from people who want to make their genotype public in a long, long, time. Has the steam run out of that project? You might hear from me again with a subtle twist on this in the near future.
