I agree somewhat - I do respond to people who have contacted me, though no one has responded to me. I thought that the dna would help to solve some brick walls and had males on both sides that were brick walls do the y-dna and all of us do the family finder dna. I proved that my brother is my brother and cousin is my cousin :) Not really what I wanted. Perhaps down the road I will have more luck.
I think going back to paper and traditional research works best, unless a person just happens to get lucky.
