Blind Links are always "in the eye of the beholder"
...but even the first one could be called blind... depending on your view of the surfer and where they came from...
"Join this site" ?? is it your site or theirs?
"take the free tour" ?? again take the tour of your (free)site? or theirs?
At leat with links like that.. you wont end up with ratios like Plateman's...
