Although I have long left my Wikity, one of the practices that continues is the interlinking within my work. I often link back to other posts. I kind of see this sort of activity as about maintaining my memory.
I was really taken by this quote by Ryan Holiday:
As a researcher, you’re as rich as your database. Not only in being able to pull something out at a moment’s notice, but that that something gives you a starting point with which to make powerful connections. As cards about the same theme begin to accumulate, you’ll know you’re onto a big or important idea.
