I Agree with u PR is not important google also gives less priority to PR.most important is Good Quality Content and Quality back link is most important.
SERP is more important than PR, in my opinion. This is because users are more likely to click and visit pages on the front rather than dig through the entire search results.
This will never happen. Google has never discarded the importance of PR. I have never heard that Google is in secret plan to underplay the value of PR. It has been invented by Google and I think it is here to stay.
