It seems that people get too hung up on "my work, my tree". It's not a contest of who has the largest or "the best" tree, though some seem to go that route. I think of it more in terms of uncovering the truth.
Yes, you put in many years of research and built a well documented ancestors' tree, are you going to take it to the grave? What's the use of having it hidden or only shown in private to a few? It's your right of course to do that, but I would lighten up and think of it more in terms of researchers displaying/publishing their work for all to see.
I think that quite the contrary, having your research out in the open especially if you have done a great job with proper documentation, will correct errors that others may introduce now or in the future and will survive the test of time... This could be of particular interest when remote relatives bump into your research now or years later...
I for myself am very thankful to a couple of relatives that worked on their tree and made it possible for me years later to connect my research to theirs, many years after they have expired...
Obviously that's my opinion, quite a few seem to disagree.
