Most of these ideas for improvement are very good and, in some cases, very overdue, and if we were dealing with a genealogy company it would be worthwhile sending them in, but by my reckoning Ancestry haven't been that for at least ten years now. These days they are a money making enterprise that leverages a very large database of genealogical records to extract cash from us. They masquerade as genealogy experts but it is clear from their responses to errors in indexing and in particular place names that they have no interest in actually getting things right.
I use to fill in those beta test questionnaires and have reported numerous place name errors, nothing has ever been fixed, nor do i expect it to be now.
Meanwhile we just have to bumble along with what they choose to dole out to us for an ever increasing amount of money, because, let's face it, none of the other genealogical companies can compete with the data they have.
