It depends on the level of risk you want to take on. A lawyer will tell you to incorporate ASAP. Personally, I feel comfortable going without incorporating right up until I start taking people's money. Just my own comfort level though. It's not particularly hard to incorporate, so there's no real reason not to do it sooner rather than later. It's nice to do it before you take any money because then you can open a checking account in the company's name and your finances will all be in order from day one. That's probably the biggest reason to incorporate early. The chances of being sued when you only have 10 visitors/day is extremely close to zero. IANAL though...
