[Each index card has limited space but allows multimedia (for instance, putting in a simple picture/diagram as a symbol). You can hashtag index cards, search for others' cards on similar topics, rate cards, provide links, and make "connections" between different cards (and possibly specify the kind of connection, for instance hierarchical), much like a semantic net. This gives a way to visualize someone's thoughts (and almost "surf" their thoughts, in a way). I might have some good ideas which I write as a linear sequence of blog posts---but if I write them as index cards instead, this would force me to crystallize my ideas more, and allow them to be connected in a nonlinear fashion. Some possible uses: A card could be a quote, and then a anecdote around it. I could make one index card for every book I read, for instance---then anytime the book comes up in conversation I could pull up my index card on the phone and know exactly the thoughts I have about it, and be able to talk about it. (In fact, if I write up cards on a variety of topics, they could almost be a cheat sheet for conversation. If you had a repertoire of cards related to topics important to you, then you needn't grope for words, for instance, if someone asks about an aspect of your work. In fact, maybe they could check out your cards first, and the conversation could immediately proceed to something new!) I could use it for academics: a card could be a Theorem or Principle X, and contain the information I would need if, say, I had to give a talk wit on short notice. ~oldheneel@gmail.com](mailto:holden1@mit.edu) #organizing thoughts
