Yes, collaboration, I agree, that is the thing, and it's what excited me most about WikiTree. As I understood it, the idea was that entries I made would compared with existing ones, and when two matching individuals were found, the users studying those individuals would henceforth collaborate.
I did not want to just dump a mass of data into your system and have it accepted as gospel, I wanted to find people to work with. Though my Gedcom is not pretty, I think it accurate and well-sourced, I included 164 people. The comparison report I got back gave me an average of about two possible matches for 64 people. Most of these were very unlikely, people with entirely different names, dates and location. I think I was able to find 5 actual matches, which might mean collaborating with 3 people. It took hours just to go through this list and toss out the bad matches. It could have and should have taken about 10 minutes.
