As a late-comer to reading this discussion, I just wanted to observe that some of the issues discussed (e.g.: use of married names vs birth names, and the capitalization of surnames, etc.) are argued almost solely from the viewpoint of "serious genealogy".
It is worth keeping in mind that there is an aspect of Geni which has to do with "social networking" -- i.e.: connecting living relatives. From that viewpoint, people want to search for and view names of living relatives as they are "commonly known by" -- and that may not be consistent with genealogical conventions.
Accuracy of data? Of course. But also anything that encourages the "casual genealogist" (which is virtually everyone with a Geni account, perhaps) to provide and maintain accurate information.
