Heh! Can someone else chime in? I used to link to my sister's tree when I first started.. then I realized that was pointless even though she is very accurate. I turned off tree hints in FTM but I do look at them on Ancestry. I look at the tree and sometimes I write to the person and ask them a question. And sometimes I tell them that they have a child that died before the mother was born. But they never answer that. BUT I have met a valuable resource through other trees also. Guess what.. he only puts his people and info found on ancestry in his tree. He never posts his real sources. I don't really think it is anyone's business what my sources are. Of course I know I should have good ones but if people want to know they can ask me. So to answer your survey question, linking is a bad idea.
