The flaws highlighted center around some of the assumptions made by the PageRank.
All the links are created equal: The problem here is that the surfers just don't hit on hyperlinks at random, we read the hyperlink, mentally calculate it's value and then click on it. If this is so the How come all the links are equal?
Bored Surfers Go to Random Pages: True, that we sometimes get bored with a page and move on to another. But, the next page is not chosen at random, rather it's carefully chosen.
Bored Surfers Only Go to Trusted Pages: While it's true that bored surfers don't go to random pages, rather think and then move on, but the page they choose might not necessarily be a trusted one.
Pages Change and Lose Value at Same Rates: The pages can lose value during their lifetime but can they at the same rate. There are a myriad factors governing each pages' popularity and each one changes in value differently.
PageRank Calculations are reliable: This assumption talks about the 'blocked' PageRank," however the patents application suggests that these aggregations are not perfect.
The User-sensitive pagerank patent application would include various aspects of user behavior to calculate a better PageRank. These aspects pertain to Link Weight; Likelihood of Randomly Leaving to a New Page and Satisfaction with Found Pages.
This patent again underscores the need to design websites which intrigue the visitors to spend a longer time at the website and explore it. However, other aspects such as the usability is important too. There have been many discussions about the PageRank and many people seem to think that there is a need to replace the PageRank with something superior, it seems that we have it already.
