DAE Wonder where some Redditors find the time to engage in commenting

I see all these awesome and thought provoking comment threads that can go on for quite a while and I just wish I had the time to put my two cents in and get responses. But I find what little time I do have during the day is taken up by browsing and just reading barely 1/4th of the comments. tl;dr - Where do you people find time to comment!
