The root of great companies is make meaning vs. make money.

Pursuing your passions makes you more interesting, and interesting people are enchanting.

Great leaders are paradoxical. They catalyze, rather control, the work of their teams. They have an overarching vision for the team but are not autocratic in the realization of this vision. Their eyes are open to whatever results occur-not just planned goals, because serendipity is a great innovator.

Klout and various measurements of influence are fun. I love to see where I score on them, but there's a computer algorithm behind the calculation. If there's an algorithm, it can be gamed. Even if it's not gameable, you have to take a leap of faith that the number of followers, retweets, mentions, whatever really mean something.

Great teams are usually small-under fifty in total head count. (There are few examples of a team made up of hundreds of people who created anything revolutionary.) Big teams aren't conducive to revolutionary products because such products require a high degree of single-mindedness, unity, and unreasonable passion.

A 50-year-old company can innovate as well as two guys/gals in a garage.

My recommendation for SEO is very simple. It’s Write Good Stuff. In my mind, Google is in the business of finding good stuff. It has thousands of the smartest people in the world, spending billions of dollars to find the good stuff. All you have to do is write the good stuff; you don't need to trick it. Let Google do its job and you do your job.
