Sorry, I can’t agree. When the errors were first released I had a similar reaction. I was annoyed at a Find A Grave mistake, and overwhelmed by the number of new errors. However, working with these errors has taught me the usefulness of FAG.
The accuracy and usability of FAG is very much dependent on the time period we are talking about. For profiles of people who died within the last 100 years, it tends to be very accurate and very useful. They usually have a picture of the gravestone. The profiles are often created and sourced by near family members, and may be the only accurate source of data on a person. For pre-1700 profiles the error rate is equivalent to ancestry.com.
Fact of the matter is, in my experience correcting errors, FAG has been vastly more accurate than wikitree. Wikitree was created by the uploads of thousands of personal gedcoms. The result is the vast number of accumulated errors from out of date sources, typos, guesses, estimates, incomplete data, etc. found on personal trees form the basis of wikitree.
Yes, I know you all have an anecdote where you are right and FAG was wrong. These turn out to be a small minority of FAG suggestions. Yes, I know Data Doctors make an occasional error by using incorrect data from FAG. Frankly, the occasional mistake a Data Doctor makes is vastly out weighted by the thousands of corrections and improvements they make. I might ask, why are you using a known inaccurate source? Why do you not even bother noting the source you put on the profile is in error?
In cases where there is a conflict in the data and it turns out wikitree is correct, just mark it as a false suggestion and move on. It is not complicated.
In time these errors will go away. They will correct the errors in wikitree, or they will be marked as a false suggestion. Wikitree is vastly better than it was 2 ½ years ago when I joined, in large part due to the efforts of the Database Errors Project. Without it, wikitree would never rise above the garbage found in the LDS ancestral file, ancestry.com and geni.com. Thank you Aleš.
