I was watching this happen last night but was too tired to post about it. My sites were bouncing all over the place PR wise. Interesting - I posted somewhere else that the next PR update wasn't due for another month - ho hum.
That means my experiment with PR6 comment links has proved that comment links are shite - the ones I got are now 2 months old, were quickly counted by G, do-follow - PR6 on the post page. The sites I got them for have NOT improved one iota, not in PR or in SERPs position. Go figure.
