Yesterday I posted that I do use the shaking leaf hints at Ancestry.com. I wrote about the hints that I was given on a person and the new info that I had and how many other sources were not hinted.
One problem that I do have with Ancestry hints is that they are for everyone in your tree, so you will get hints on your 7th cousin 5 times removed's wife's grandfathers second wife's father as likely as for your great grandfather. This isn't entirely true, because the hints are generated when you look at a profile in a part of the tree but it happens more than is convenient. When you go to attach the hint to get it off the list, you get more hints on a line you may not care about. Sometimes it would be nice to be able to sort the hints to show blood relatives only.
My hints climb faster than I can hope to clear them. Yesterday I had 112, 050 and today I have 112, 526. At the end of the day I will probably have more even though I will have spent hours attaching hints to profiles.
