Reading about the latest change in pagerank by Google I had to check mine. I must say I was fairly confident that it still would be at 6, but no. Oh no! Google cut me in half! Down to three it is. So far no change in incoming traffic. I get about 80% of my traffic from Google. I do not participate in any link schemes or anything like that so not sure why Google changed my pagerank.
At least I am not alone:
