I would say that those ethnic groups more likely to have migrated to the U.S. would be grossly overrepresented in such a sample. That in itself is enough to skew any result. For example, more Italians and European Jews, fewer Romanians,Turks, Bulgarians,I raqis, etc. (just to mention some groups having a fair amount of E3b)
Don't get me wrong; it's always great to have data, even if it's a biased sample. We just need to be aware of the lomitations in drawing broad conclusions.
It's too bad that there seems to be no mechanism for folks who have already "maxed out" on their own personal testing to sponsor just a basic 12-marker for someone in a less-developed part of the world. Just a thought...

More to the point, how would a difference between rich and poor
E3b1a2 folks that is strong enough to actually bias the calculated
modal arise and persist.
