"Traditional linear reading is highly inefficient. This comes from the fact that various pieces of the text are of various importance. Some should be skipped. Others should be read in the first order of priority.... All linear texts can assume that the reader is familiar with the preceding sections. This makes them context-poor." - Piotr Wozniak in the Incremental Learning Manual
"reading: this is the first stage where knowledge makes an actual intimate contact with the brain. Traditionally, it is streamed into memory in a more or less linear manner (i.e. paragraph after paragraph). Incremental learning helps you delinearize this process and optimize reading by enhancing knowledge selection and prioritization concurrently with reading. For example, you should be able to say "This paragraph can be processed later" or "This paragraph requires utmost attention right now" or "This paragraph can be skipped for good even if I decide to read the article again" or "I want to read this paragraph again in three days and in more detail" or "I want to mark this paragraph with lower priority and come to it only after all higher priority paragraphs have been processed", etc." - Piotr Wozniak in the Incremental Learning Manual
