I think people are forgetting to ask the key question - Cui bono? Who benefits?
23andme definitely benefits - all the data they have collected is very valuable, and they intend to sell it to pharmaceutical companies etc.
On the other hand, working in genomics, in my opinion the benefit to any one person having their genome tested in this manner is minimal. The simple reason is that most genetic alterations have low penetrance for phenotypes or involve complex interactions.
