How effective do you believe buffer sites actually are? What specifically is it which makes for a good web 2.0 buffer site? How effective and what kind of results do you think we would find if a domain had a maximum of 10 links all from 10 web 2.0s which have each been blasted by many SEO tools? Do you think those 10 web 2.0 links alone could prove to be very effective? Or is the more direct conventional method of blasting an aged money site more effective? What do you guys think would happen?
