50% are < 1000 words long texts written by me, transcribed from an audio/video/paper source or saved/clipped/copypasted from elsewhere
20% complete webpages or complete articles deemed important enough to save a copy for later 10% graphics, annotated images and PDFs 10% oneliners and quotes 10% todo-lists, task lists, shopping lists, etc.
Every new piece of information I have been exposed to and deemed important enough to return to later has gone into my Evernote inbox, from where it would be weekly sorted into an appropriate notebook by subject, life area, etc. Most important ones are tagged for regular review. Everything else gets some regular dedicated random browsing time, and is often discovered in research when preparing presentations, writing or thinking about any particular topic. There are 80+ notebooks in 10 sections.
Organizing this corpus efficiently and engaging with it with an appropriate interface would effectively be a multiplier for the ability to utilize knowledge and experience. Interacting with such data accumulated over decades through a combined voice assistant / mind map / dashboard / big screen (Microsoft Surface style) is a futuristic idea of knowledge work - the only question is whether there is a large enough consumer user base for such an infovore/generalist/researcher approach to information.
