“In Evernote, Notion, and most note taking tools, your information lives in a hierarchy. Evernote’s is based on three levels: Stacks, Notebooks, and notes. Each note lives in one notebook, which lives in one stack… In Roam, notes live nowhere and everywhere… Each note has relationships to other notes, but no note lives *inside* another note or notebook. All of the information is fluid in the sense that you flow between notes based on their relationships, not because they’re all in the same folder or hierarchy.”

We can explore the ways in which our attention is generated, manipulated, valued and degraded. Sometimes attention might simply be a lens through which to read the events of the moment. But it can also force us toward a better understanding of how our minds work or how we value our time and the time of others. Perhaps, just by acknowledging its presence, we can begin to direct it toward people, ideas and causes that are worthy of our precious resource.

Attention is a bit like the air we breathe. It’s vital but largely invisible, and thus we don’t think about it very much unless, of course, it becomes scarce. If that’s the case — to extend a tortured metaphor — it feels as if our attention has become polluted. We subsist on it, but the quality has been diminished. This is certainly true in my life, where I’ve become so reliant on the constant stimuli of our connected world that I find myself frequently out of control of my attention. I give it to others too willingly — often to those who will abuse the privilege. I’ve also become dependent on the attention of others, even those who bestow it in bad faith. I’ve become a version of the very person Mr. Goldhaber described in 1997, for whom “not being able to share your encounters with anyone would soon become torture.”

we tend to ignore his favorite maxim, from the writer Howard Rheingold: “Attention is a limited resource, so pay attention to where you pay attention.”
