Something I like to do recently is ask Fable to make me a skill out of someone’s publicly shared knowledge.
If someone writes about say marketing for developers, I send Fable a link to their articles and tell it to make me a skill out of it.
Then before sending a marketing email for example, I ask Fable to run it through that skill and show me how it can be improved.
This applies to anything really, writing, designing, etc. as long as there’s some publicly available data that you think is good.
So again, taste plays a role here as well.
