Thanks for the input. I'm working on my startup as well, so don't be too worried about how I'm spending my spare time.

In fact, in one way, I made this so I could spend more time on my startup. I found myself wasting too much time reading Hacker News. Either I was procrastinating and refreshing too often, where I found it hard to either identify what story was new that I hadn't seen, or which ones I'd already seen but did not interest me. Or, I was going back and reading simply so I wouldn't miss anything, since stories tend to trail off pretty quickly unless they get a lot of votes.
