I've used Ancestry a bit this morning. I think I will get used to this new way okay, but it does not seem to simplify anything or make it better.
Regarding hints...if someone else incorrectly adds a source to a profile, then Ancestry is programmed to offer you the same hint, even if it is obviously incorrect. I don't like that either. I suppose that is why it is good for us to say why we rejected the hint, but that got so tedious, I stopped doing it after a while, too. I have written a few people who have incorrect sources attached to their trees and, therefore, incorrect information and/or incorrect connections, but I rarely get a response. The same thing happens at FamilySearch, which is worse, since it's a "one-world tree." I try to leave notes on FS profiles when I encounter bad info/relationships whether they are due to incorrectly attached sources or not. Again, little response. I sometimes detach incorrect sources there. I've seen the same sort of errors in sources and/or connections here on WikiTree, but at least we are usually more collaborative in making corrections.
