amazing, an article that was written about 16 hours ago (in www.itpro.com) is now showing PR2. how can this be ?!
The real Question is "Whether you observed increase in rankings along with PR or not "? I am sure you will get your answer.
well, it was posted on a site who's homepage carries a rank of 5. With the right internal linking, any page can come up in rank rather fast. Just remember that page rank is not really what you need to look at, it's not all that important.
