I noticed that Google updated most of the website or blog page rank on April Fool(1st April) but I just get my update today. My main blog page rank is maintained while another blog LimPek.com (3 months old) increased from page rank 0 to 2. I think the data centers are still in updating process because I can see certain site has PR 3. But when I check with a page rank tool it showed PR 4.
At this moment, I feel very happy because my main blog is stable at PR 2, inner page doesn’t have much PR though, most remain 0 and little have PR 1.
