I thought this was a very good article:

QuoteI am pretty public about no longer believing in Whitehat vs Blackhat SEO. If you're doing anything to try and get more links to move up the Google rankings, you're 'manipulating' the algorithm one way or the other. I've got to the point now where I've just accepted the state Google is in this year and started following the crowd for what works. Myself and my clients have sites on both sides of the fence (old with a ton of natural links and new with very few links) so how Google swings doesn't make much difference to me at all.
I can't remember where I came across Glen, but it was in the pre-Viper Chill days and he's about the only SEO left in my RSS feed (which, okay, I never read, but that's another story). He writes rarely, but when he does, it's in-depth and insightful. 3000-4000 word posts are not uncommmon
vague recollection he may have cropped up on TW at some point
