Ranking search results using Pagerank requires a time lag. Until recently Google preferred pages old enough to attract others to link to them.

To identify fresh information, analyze the attention streams of people when they consume it.

We need to be careful about issues that become superstition: “we talked about that once and it didn’t work so that topic is done,” “maybe that would be better but it’s too much trouble” or (my favorite) “that couldn’t possibly be efficient enough to be justified.

My reality is that it is basically not possible to make a living in the Long Tail. The long-tail theory is a basic and profound truth that I happily embrace as a consumer. But as a producer and creator of Long Tail content it basically spells out my doom. I have the same issues and problems my predecessors did. I need to find multiple large national distributors if I hope to even come close to making a living at this game. And I need to produce fresh content on a reasonably frequent basis.
Jeff Bach argues that the long tail is good news only for large aggregators

If you don’t believe Euclid’s proof that there are infinitely many primes, then I don’t know why seeing a formal proof in ZF set theory should quell your doubts. You could deny Modus Ponens, you could demand a formal proof for the assertion “The infinitude of primes is a theorem of ZF” itself (ad infinitum), you could refuse to identify the formal notions of ‘prime’ or ‘infinity’ with the informal ones, and so on.

‘Work’ is usually doing what others tell you to. ‘Life’ is doing what you want. The modern fixation on ‘work-life balance’ becomes irrelevant if you work for yourself.

In order to get tenure you must not arrive at conclusions that members of tenure committees can disagree with. In math and the sciences, you can prove what you’re saying. Or adjust your conclusions so you’re not claiming anything false (“6 of 8 subjects had lower blood pressure after the treatment”). In the humanities you can either avoid drawing any definite conclusions, or draw conclusions so narrow that no one cares enough to disagree with you.
