Earlier today, Google once again has just updated PageRank. The last recorded PageRank update was in November of last year. I had written a blog post about the expected dates of next Google PageRank Update for this year and it seems that our prediction for the first update this year is correct.
TutsKid.com is still PR4 but there are some changes on my sites, especially with any inner pages. Most of my posts got the pagerank 2-3 including most of the tag pages. My other Trip and Travel Blog is not updated for 2 months yet maintains its pagerank of 3. 
For those not familiar with Google PageRank here’s a brief explanation
PageRank is a rating from Google of your webpages on a scale of 0-10, with 10 being the best rating. It is updated every 3-4 months. So, the next Google pagerank update is expected in the months of June and July 2013.
Let me know how you did on this update
Closely related to this wonderful article I have developed a website worth estimation algorithm that uses Google Page Rank as one of main evaluation parameters:
