If I'm not researching, I'm working on what I researched or working out how it could relate to me. If I think up a mechanism, I stay on the internet until I definitively prove to myself if someone else already did so or not. I do have the 'standard' list of obsessions; cars, computers, automation etc, but they always lead me to new, less pervasive ones. I don't really think it helps me with my work, but if I expand the body of work to include all the other thought-intensive activities I'm part of, I don't think I could live without my amorphous blob of random knowledge. I used to read books compulsively, sometimes more than 3 lengthy novels a week, which I still do on occasion, but less and less now that I fully realize how much more trivia is available to chew on straight from the internet. My quest for understanding has taken me back into the computer, and now, along with programming, I participate in tests, evaluations and modifications of the very same software I use to absorb all my assorted tidbits. On a normal day, between electronics, work, cars, bikes, science news and whatever else I stumble into (I'm my own StumbleUpon) I have 50 some tabs open in my test build of FireFox, which I've been compulsively modifying, testing and 'improving', driven all the while by the same empiricism that keeps me Googling.
