Unfortunately, it lacks any real content and depth - it may as well have been written for Reader's Digest.
At first I tried hard to make my blog well-integrated and popular. I used all the usual SEO techniques and developed a mass of followers. Once I was there, I stopped caring about these things and voila - I am still popular. My position as lead developer of Tumblr might be related.
My expectation is that the less time he spent on gimmicky SEO crap, the more time he had to actually make things that someone like me pays attention to.
