While I was one of the first to try out this commercial DNA service, I certainly haven't been the last.
At last count, 23andMe has 35,000 customers. Curious people gave their spit, so their DNA could be unraveled and give them more information about their health and about their family.
The results are given to customers through an online profile. By logging into the Facebook-like profile, the customers can see information about their health risks and have access to clues about their ancestry.
But the services face an even more fundamental problem: in most cases, the current level of DNA scanning technology and science is unable to offer meaningful predictions about the risk that a person will get a disease.

But, you'll have to decide quickly if you want to spend money on a DNA test. The offer is only valid today. And you can't exactly go on a shopping binge because the company has capped purchases at 10 tests per person.
