We are each our own editors. Amidst the heightened noise and confusion projected at us constantly, we all need strategies to identify information as valuable and valueless.
If folks are interested in telling people information, but not interested in 1. making it relevant or 2. making it memorable, then their motives are selfish, and they can be freely disregarded.
If you're trying to teach someone something, and you are doing it for *their* good, it would be wise to prioritise these factors.
