I am still getting an almost constant complaints from various researchers worried about "people" changing "their data" online. This concern seems to come from relatively sophisticated researchers that are fearful that if they put their data online all their research will be damaged or changed by people who obviously do not know as much as they do about the subject matter. The issue of the ownership of genealogy files is like something out of the Night of the Living Dead. They just keep coming at me day after day (night after night?) with complaints about online programs and how their file will be so badly misused by relatives. Wait a minute, how could they be concerned that someone might change their data online if they don't have their data online?
On the other hand, I get the idea that these people who are concerned with the integrity of their data may have an overactive sense of their own infallibility. I can only guess but this attitude has to arise as a result of being so isolated from any others working on the same lines that they are researching that they begin to think that anything they conclude has to be correct since no one has ever pointed out the limitations of their own research. Unfortunately, the cure for their fears is the very thing they fear; a good dose of criticism and suggested changes. I long ago lost any allusions I might have had at one time about my own accuracy. As the commentators to this blog are usually quick to point out, I have my share of typos and lack to proper sentence structure. I have also spent a significant amount of time correcting my own genealogical errors.
One researcher approached me because he was concerned that a Family Tree on Ancestry.com could be changed by anyone. I think he may have been confused with FamilySearch.org's Family Tree program. As far as I am aware, unless you invite collaboration, no one others have access to your Ancestry.com Family Tree.
My suggestion to these people is that if they are uncomfortable with sharing their Family Tree online, that they publish their research in a print book. That way, no one can change the information.
Sorry about this rather short rant, but it seems like I am immersed in a pool of researchers who are certain that putting their data online will lead to disaster.
