Partially agree. Things like Pagerank, us IM peeps get hung up on it, but in reality don't worry, if you have good content and other people link to it, you will get PR.
There was a post recently about google updates, the advice was don't panic. It's the same thing, we spend too much time panicking. Learn the rules, play the game and relax. Take some risky shortcuts, and then its time to sweat.
Online reputation is 1000 times more important than how many like's or +1's you have, but they can be used as indicators of what does or doesn't work.
He may knock KPI's as mechanical, but you need some kind of yardstick to measure of. It doesn't have to be corporaty pie chart full of waffle, maybe a basic spreadsheet with what you deem to be acceptable goals/outcomes/conversions.
maybe forum post = more exposure
2 FB likes on new blog post = shows content is of interest
negative feedback or reviews = issue or problem that needs addressing
I can see what he means by mechanical SEO, eg must have more crappy low quality links.... must spam more blog/forum comments, and we see plenty of examples of it. But I think this is aimed at more of the bottom end of the IM spectrum, link builders etc, rather than people who take IM seriously, or thats how I read it
