Madness Monday - 03-01-10

I guess my madness today comes from a record I posted on my ancestry.com tree.  I added a record to my tree, then had to leave for an appointment and wasn't done with adding the source for the record, came back from my appointment to finish adding the details for the source of the record, and someone had already attached the record to their own tree!  Don't get me wrong...I prefer to be the type of genealogist that shares information and records that I find.  It just made me feel like a vulture had swooped down and grabbed what they could.  I have debated about changing my tree to private but I really would rather share.  If I change it to private I guess it would force them to contact me but I know some people aren't comfortable doing that and I understand, I really do but if I find something on someone's tree that I could use I usually try and send a message to them to let them know how we are related and give them my email address so we can share information.  Maybe I am just being sensitive but man I wasn't gone an hour!  So do I continue to share my ancestry.com tree or go private??
