Stock and flow

But I actually think stock and flow is a useful metaphor for media in the 21st century.

Here’s what I mean:

• 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.
