In hierarchical link order a site's domain will always have a higher PR on all its Pages/Posts. (e.g example.c0m has PR 5 - example.c0m/pages has PR 3 - example.c0m/blog/posts Blog post has PR 2). - You know what I'm taking about..
Last December 5/6, 2013 (Depends on your country), Google decided to update Site's PR (Mutt Cutts is a level 1.5 Master of Disguise )
Just yesterday, I was navigating through my client blog posts. I decided to do run down routine check on anything and everything and I suddenly got stuck in confusion when I notice that 1 particular blog post link has the same PageRank as that of its Domain. In shock I did a PR Check and also decided to ask my client if the PageRank I'm seeing on one of our blog post is the same and the result of the PR Check I did. In my years of SEO I haven't experience this and I haven't heard nor read about this. (Probably because I am not putting much attention on PR, I suddenly became an outdated SEO Specialist or I'm still too naive on my profession. Either of this it's still a good knowledge gained and I'm sharing this here.)
Please don't get me wrong and try to read first to avoid arguments as it is really hard for me to convey what I really want to say as English is not my native tongue and sleep deprivation is consuming a lot of my energy.
Hopefully I can hear some of your thoughts. I know a critic will reply and will say bla bla bla bla..
