Hmm...that's a tough one to gauge, considering I hardly ever sleep to begin with. Plus, there's the fact that I rarely log out, and all kinds of other factors that make it impossible for me to rule out the latest time I've spent on here. If I had to guess, though, I'd say 7am (after having been on for two days straight without a break). I [may have] hit this milestone during the summer of '11 when my posts-per-day reached its peak...
