Although a really interesting post, I beg to differ at one point at least.

The materialistic aspects of startup knowledge definitely have a half-life, sure enough.. but when you are talking about things like "fail-fast", I don't think they're "fashionable."

Startup wisdom - which stems from knowledge - cannot go stale in most cases. Intricate details like what kind of a metric you use to see what affects the conversions can change but the very fact that you should track your conversions doesn't change for centuries or more.

If this is what you did mean by startup knowledge, thanks for writing this! :)
