Hey Mark, No follow has nothing to do with the viewer on the site. it is a tag that is for the search bots only.
Basically, a link to another site is how the search engines determine the relevance of that site for search rankings. The no follow tag is meant to tell search that you are linking to something, but don't want to pass page rank to that page. It has nothing to do with what a reader on the site will see.
Really, so many people abuse it that it is largely ignored. I have pages that rank highly with all no follow links to the site.
