Page Rank

Two weeks ago, I was frustrated since my other blogs, which has PR3 reduced to PR2, and I was annoyed since I am getting fewer offers for me. I knew that if I take offer that their link, which has lower rank or no PR at all, it could reduce my PR or will be possible to go back to zero. In my bravejournal blog, I take an offer which their site has the same PR of mine and now still PR3 and I hope it will stay like that for a while and it could be if I am not greedy taking an opp… which has no PR. I hope when the Google will update again it will give PR to my other blogs. I am still thankful that I do still have blogs at least PR2 and 3 and other blog went back to zero and recently they gave it PR1 at least it’s 1 than 0. I am just wondering when the Google updates again, anybody knows? Let me know as I am waiting and it gives me thrill.
