Agreed. My family history spans 3 continents, so tracing the people gives a very personal connection to history. Who knows what could be revealed as the site grows?
However, I do warn my relative, who has spent much effort on this endeavor of hers, and shared it with Ancestry.com, while paying for the privilege to do so, that she should keep all the things she finds through Ancestry on paper and in other formats for herself, and not to rely on Ancestry to maintain that information for the time spans she is used to dealing with. Fortunately, as someone who gets frustrated when a particular lead into the life of some obscure distant family member turns cold because of missing documents, this isn't too hard.
