It's presented in an experimental new media form, a mnemonic medium which we believe will make it almost effortless to remember the details of what you read.
It does this by building in spaced-repetition study. As you read you're tested on what you've read. This helps you consolidate the information, and be sure you've understood the basic content.
Then, in followup sessions you'll be re-tested. By spacing the sessions appropriately, you'll consolidate the ideas in the essay into long-term memory.
This is a first stab at developing a mnemonic medium. We're hopeful we can make it a lot better. It's part of a larger research project, aimed at developing new media forms for augmenting human intelligence.
Sorry for the trouble, Jay. We'll build a real UI for this, but in the meantime, DM me with the email / phone number you want to stop receiving notifications, and I'll take care of it for you!
