Really good article John,
A lot of good info in one spot instead of having to scour the web / forum.
One thing I am not sure of though is that some directories may not release
PR onto some of their pages, is it still worth placing a link on these?
I am not saying that google
PR is the be all and end all but sometimes I feel loathed to pay a directory if their the specific page I am being listed on isn't listed in google.
