 bits of work that we, I mean, in some ways what you do on Facebook or Twitter or even crowdsourcing are little bits of work. And we were getting, you know, as a scientific community, we were getting very smart about how to take these little bits of work and stitch them together into something bigger. And I got interested in how I could do that for myself so that while they were napping or doing something else, I could be doing something that was productive and valuable to me.
