Strange google update

Just noticed the post by Jim in DP regarding the backlinks update.

so checked all my sites and i am happy in a way that most of the sites are showing an increase in the backlinks.

strangely though, old sites are reporting no changes whatsoever but new ones started in the last 15-20 days have shown a nice increase.

these were just dormant domains without any sites and now they have a good backlink to start off with.

wonder what google thinks, but whatever it is, i am happy
