I believe the new feature that Ken Chahine was referring to in that particular blog is Ancestry's "groundbreaking" Circles.

I have 4 circles. Each is one half of a 4th great grandparent pair. So 2 pairs total - all well researched and well documented. Since one has to have all the info already to be included in a circle, there is no possibility of a brick-wall break-through that I can see.
