I'm careful as well.. I trust ancestry more than I do that site.
Same here, as there is enough indexed and scanned info, to provided enough documentation in any cases.
the ability to link those references and documents to individuals and trees helps tremendously in separating the creme from the curds.
Having the ability to see scanned documents of ancestor vital records from England 400 years ago is beyond cool.
OTOH as Ancestry has become a behemoth and a monopolization of the on-line aspects of the hobby, there are several things they have done to anger me.
(1) Abandoning the FTM (Family Tree Maker) Program. This is their way to force the genealogical community to manage their trees/data through their system (cloud). Disgusting.
(2) If you have noticed Ancestry is getting ready to tinker (screw up probably) Find A Grave. F-A-G was probably the most innovative and near thing to come out the genealogy field in the past 15 years. It has a lot of info, grave pictures, and data, that wasn't found anywhere else. Mark my words, within 5 years Ancestry will find a way to charge customers for this, and screw over the multitude of people who contributed to this fine program.
