Has anyone else experienced a drop in PR that wasn't really expected? Things were looking good until the earlier PR update, but quite a few sites have lost a point, despite getting some good links recently. I guess other sites must be adding quality links at a higher rate, either that or a load of sites have been kicked out or suffered PR losses.
Could just be things aren't stable yet (just seen it bounce up again), but it's a new experience for these sites.
