SEOptimise.com has a bit of video up from SES London about what Google ought to do about Black Hat SEO's. While I like some of the answers, and others are compelling, I have trouble with the whole Black/White Hat view of the world. One fellow in the vid correctly points out that most SEO effort is "light grey" anyways. In my view, any SEO that's not totally organic has a "light grey" aspect to it, but SEO can be done ethically, nonetheless. What do you think?
