It might be fair in your opinion but does not fall under fair use law.
That is nice it brings him traffic but that is the only reason it is ok to use when it does fall under fair use and your post is not made in the form of something that would be considered fair use.

So no matter how much traffic you bring him it does not change the laws.

Your post is not commentary, search engines, criticism, parody, news reporting, research, or scholarship so no matter how much traffic you bring him it does not change anything.

whatever though, I said you left a link and said it was a quote. lol
