I notice these days that I can spend hours at my computer, in a cloud. A swampy blur of digital activity, smeared across various activities and media and software. Emailing, writing, tweeting, designing, browsing, taking calls, Skyping, Facebooking, RSS Feeding - all blurred into a single technological trance. I seem to switch randomly from one to the other. But actually is there a subtle hierarchy in this cloud? Do I prefer some distractions over others?
