The fact that you feel like you "know" SEO like the back of your hand, etc.... is a big give-away to your problems, it results in complacency.
I did my final project at uni on SEO, have worked in-house for a large multinational corporation as an SEO, have worked now in an agency for three years doing nothing but SEO, subscribe to every blog that's any good, read every book that's any good, and have done every SEO course in existence that's worth doing, yet I know ABSOLUTELY NOTHING in terms of what their is to know, and I know nothing in comparison to many of the people on these boards. Maybe Mr. BigJohnson, you should consider how much you actually know, rather than how much you think you know before apportioning blame for your own lack of knowledge.
Also, If SEO is dead then why are all of my agency's clients so happy with the results we get them, which increases their revenue... maybe look inwards for the answers to your problems instead of outwards!
