I've noticed of late that most of the "links" or "resources" pages I visit seem to have a toolbar PR of n/a. I don't recall an overt announcement by Google on this subject. Is this a recent change? Have they actually devalued these pages in terms of the link equity they can pass?
These are not new pages that have not achieved a toolbar PR as yet as some of them I've tracked are up to 8 or 10 years old. It's not that they are deep pages either as many are one click away from reasonable PR home pages.
Does anyone have insights into whether they have actually killed the link value passed from these types of pages or whether they are just playing with the toolbar PR.
I've gone to content exchanges recently rather than raw link exchanges so this doesn't really affect my SEO much but it would be interesting to know if they have totally devalued these types of links.
