Wow! That was quick... check out your website's PageRank, I think there was another Google PR update last July 18, 2011. This blog's PR is back to PR3 from PR2.
I thought my site lost some PR points, I guess Google corrected this "mistake". Maybe Google miscalculated some site PageRanks and had to re-update them to the most accurate PR values. =)
Thank you Google!
