Hallo Justin,
You ask what can we do as Geni better. The curators have a good function and are needed. To control your area you need a good knowledge about the language where the person you control was living. If not give that person to a other curator. Second for Germany as example, Wikipedia is not the place to find a correct information. You need the books with scientific character if it is before 1400.
