...instead of making your own buffer? Say if you wrote some quality comments on blogs and got them posted then just started blasting the shit out of the url where your link is located. Wouldn't this do just the same as making your own web2.0? Sure the link could go down if they delete the comment but so could a web 2.0. It would still pass linkjuice the same way right? Or are squidoo pages etc. more valuable cos they have more pr than some random blog?
