Ever since I started highlighting text on my Kindle, then my PocketBook, and also the old-fashioned way with pen and paper, I have been trying to store those highlights in my digital garden — which serves as a second brain for recalling insights from books I have read. I built brainfck.org to keep my collection of notes available online, not only for myself but also for others. I even added a search feature (first introduced in ce36502 and later improved in 9a23b40) that lets you search across the entire collection.
