I've never met Bill in person. But since I started with SEO in 2007, I can't remember a time when he didn't help me with his excellent and downright sharp articles. In particular, his blog seobythesea.com has been and continues to be one of the most valuable and clear-eyed resources for SEO in the world for me. I truly hope that Bill's bright mind, curiosity and steady energy will help him get through this difficult time. All the best, Bill!
