There has been a pagerank update by google recently. Unfortunately binaryday.com has suffered a drop in pagerank from 4 to 3. Couple of other blogs i.e abhisays.com and bishtblogs.net have undergone a similar drop in the pagerank. I am not sure if google has decreased the pagerank of blogs across the board or there is something wrong with binaryday itself.
