Well, they're accurate but not precise.
What's useful is using the "DNA match" features of various websites to track down genetic relatives and use their research to flesh out your family tree beyond the point they intersect.
What's not useful is to use them to say "I'm 30% ____". It just doesn't work that way. Even the Ancestry results that show I'm like 30% "Ireland/Scotland/Wales" shows a whisker plot when you click in that gives a margin of error of +/- 35%.

It's the accuracy of the conclusions drawn from those results that is more difficult to offer... Your thoughts?
