Ted Nelson is a famous computer visionary, best known for coining the word hypertext. He was not the first person to see the huge potential of computers to enhance human thought, but I certainly learned about that from him – his book Computer Lib ∕ Dream Machines was an early influence. That was the first time I encountered the notion that computational technology could be a vehicle for thought and expression, that it was a medium and could serve as a prosthesis for the mind.
All this hypertext goodness is based on Logseq, a newish note-taking tool which I've recently adopted. It's similar to Roam and was started with Roam, but after a brief fling with that I've decided that I can't use it, and Logseq is the best alternative. Because these new hypertext tools are a bit deficient on publishing tools I rolled my own starting from an existing open source project.
