Where Good Ideas Come From, published 2010, is one of the spiritual prerequisites for how we designed Froots. If you've built a tool-for-thought in the last decade and you haven't read it, you've probably absorbed its ideas by osmosis from the people who did.
Johnson's central claim is that good ideas come from environments, not minds. He inventories the environments — Renaissance Florence, Enlightenment coffeehouses, 20th-century labs — and extracts seven patterns that make an environment generative: the adjacent possible, liquid networks, slow hunches, serendipity, error, exaptation, and platforms. The book is not a business book, though it's often shelved as one. It's an ecological argument about cognition.
The parts that have aged extremely well:
The adjacent possible. Every idea is a neighbor of what already exists in your head. The way to have better ideas is to expand what's next door. Obsidian's graph view is a direct visualization of this; so is our backlinks drawer. A vault isn't a filing system, it's an adjacency machine.
Slow hunches. Some ideas need 7 years to develop. They need a place to live while they're half-formed. This is the single best argument for a personal knowledge system that isn't a to-do list. A note you wrote in 2019 that becomes relevant in 2026 — you have it because the vault held it for you.
Liquid networks. Ideas need to bump into each other. Small-world networks beat isolated cells. This is why we made the unified inbox — signal from your humans flowing into the same surface as signal from your notes.
The part that hasn't aged as well:
Johnson is very optimistic about platforms and open systems. He writes in 2010 about how the web is a generative platform precisely because no one owns it. Fifteen years later, most of what he praised (open feeds, interoperable protocols, coffeehouse-like comment threads) has been eaten by silos. The ideas-from-environments argument still holds; the default environment in which knowledge workers live has gotten much smaller and more controlled.
That makes the local-first argument stronger, not weaker. If the web is no longer a commons, your vault has to be. The interesting ideas of the next decade will still come from the adjacent possible — it's just that yours has to live on your disk, not someone else's quarterly roadmap.
Read it. If it's been a while since you did, re-read it. Then re-read Christopher Alexander, because the "pattern language" intuition is the hinge between Johnson's environments and any actual tool you might build.
