I came across this thoughtful analysis of the changing world of social media. The on-line magazine is published by the Berggruen Institute.
"Noema" is classical Greek for "thought". If you don't know about this, you might take a look - very interesting.
**νόημα** is an ancient Greek word meaning **thought, perception, or purpose**—the mind's conception of something.[1][2] In philosophy, particularly in phenomenology, it refers to the **object or content of a thought, judgment, or perception as it is intended or perceived**.[2]
In modern Greek, it can also mean **sense, meaning, or point** of something.[3]
