Curt Witcher (Allen County Library) was a speaker at the RootsTech 2011 conference in February. His topic was "The Changing Face of Genealogy." You can see his presentation at the link provided below.
The talk is about 1 hour so grab a cup of coffee before you start, and then settle in and enjoy. The first 6 minutes of the video deal with conference administration, but it is worth holding on for Curt.
