A while ago I worked out that if I pulled the plug today (like, cut all expenses back to nothing except a cheap host) I'd actually the most profitable 12 months I've ever had. From then on I'd still make a pretty nice income for years to come. Stuff like that helps me sleep at night
If porn quite on me, not sure what I'd do. I'd be pretty happy to be doing something new. Probably trade futures and forex full-time. I dabble in it ATM and mostly enjoy it more than webmastering.
