Hi, I have recently found out a way how to see the rel="nofollow" on the screen without looking at the source. Each nofollow link gets a specific icon beside it and I tell you, DP won't look the same ... It is excellent when checking your backlinks etc. How to install it: Run Firefox. Install the extension TargetAlert Then go to Tools -> Extensions -> TargetAlert -> Options deselect "show icons on mouseover", double click on "link ignored by search engines" so it is displayed "true". Now you will see it. You also see an icon beside PDF, mailto: etc. links - it is excellent.
I am using some specialialized script for Greasemonkey extension with same effect - it changes nofollow's to a strike-through font.
