Content drift is how a piece of linked content may change over time such that what was once linked may in fact now be very different.

An article you link to may be corrected, opinions may be changed, content may be expanded or removed, a paywall may be put in the way, and yet the link keeps steadfastly pointing. Content drift, along with link rot — pages being lost — is one of the ways that the information we have come to rely on on the internet can be gradually undermined.

Here's a thread on content drift and link rot from Harvard's Jonathan Zittrain — at least, it was a thread on it when I wrote this. Also see: The Internet is Rotting.

Bloom's taxonomy has 6 levels of increasingly sophisticated thinking skills. It was originally developed, in a slightly different form to here, for classifying educational objectives and with additional variations, dimensions and sub-levels in the full models, is still useful for teaching and learning. The hierarchy reflects, among other things, that a strong foundation for learning is knowledge.

The 6 levels in the revised Bloom's Taxonomy for learning are: Remember, Understand, Apply, Analyze, Evaluate, Create

The twin engines of altruism and ambition are a powerful force for positive change in the world.

They need to be balanced. Ambition without altruism and change may not be positive. Altruism without ambition may be nice without impact. But put the two together, for example with a mission-driven business like B-corps, and it can be a recipe for wonderful, positive, and meaningful change — and probably what we need to deal with the challenges of our times.

This lovely concept is from Richard Reed, co-founder of Innocent drinks, and I learned it from Holly Tucker's Conversations of Inspiration podcast.
