Being 18 without a real job, I probably spend far too much time. Sometimes its a half hour, sometimes its 7 hours, it really depends on what I'm finding, and how motivated I feel. Although I'm not domaining the entire time I spend online, I'd say a good 60-70% of my online time is spent doing some kind of research. If I'm not doing that I'm probably working on one of my projects, one of which relates to this industry.
