I have checked some websites of mine and some of the competitors and this is definitly a pagerank update. Some of mine gone up 1 point from PR 0 to PR 1 some went from PR 1 to PR 0. Share your thoughts.
Confirmed, definitely PR update for two of my sites - one up and one down by 1. All the rest are same.
My breaking news site has been updated from PR 0 to PR 1 just within two months of its launch. I am on cloud 9 today
