Flow is the feed. It’s the posts and the tweets. It’s the stream of daily and sub-daily updates that reminds people you exist.
Stock is the durable stuff. It’s the content you produce that’s as interesting in two months (or two years) as it is today. It’s what people discover via search. It’s what spreads slowly but surely, building fans over time.
This ties back to my thoughts about perennial and annual work.
A good reminder that making the long meaty work isn’t enough, you need to do the connection work, the in between work that gets attention.
