(A commonplace book) is a means of collecting and storing all those bits of information that make our lives interesting. It could be a photo, an essay, or a quote. Regardless, it’s important information that you want to mark and save for later. (...) Sharing things in my corner of the web makes them also form a part of my identity. What I share, to a large extent, is who I am. It’s how I communicate with you even if I’m not able to talk to you everyday. (...) This is why my blog is my public commonplace book. The collection makes me, me. It’s on my domain. It’s free. That’s all important because if I lose my shared items, I lose a part of that core identity.The destruction of a sharing service means I would also lose the ability to flip back through a history of my thought. Those long-forgotten hunches would stay forgotten and lost to history. Without a commonplace book that you control you’re gambling your ability to learn and grow from your current actions.
