First, I've never disagreed with you on that statement. Google themselves share that
PR is the basis of their system. So you have at least one person agreeing with you on this site.
Now, onto this post. I think that it comes back to the truth. Google has shared this for quite a while, and I don't see anything changing anytime soon. I think truth be told, many
SEO "specialists" or designers simply don't get to this level of information. Most don't take the time to dig this deep, and therefore are unable to honestly share whether this is an issue or not.
Lets take the all holy grail of "link-building". If you're searching for "links", don't you search for the best pages with the highest
PR that is on topic to your site to get a link from? Doesn't that alone attest to the importance of
PR?
I rest my case
