1) 6 years

2) 8 million monthly uniques

3) Hard to say. I can take a month off and it'll probably go fine. If it crashes, I'm on it 24/7 (if I care for my wallet). I do work on it full time, but that's working on growth as well as managing the present state. I try to outsource as many chores and secondary tasks as possible, leaving the multi-disciplinary work for me.
