I assume you mean what makes a good website entreprenuer? Well I would say someone who is committed and innovative!
No, because if you're an idiot you will not go anywhere. To be successful you have to actually KNOW something about the web or about the business you're getting into. A grandma who never used the web will not make a good web entrepreneur.
I agree with passion. Cos that means you will stick at it. That means you will learn. That means you will get better.
a good founder should be thinking about the next steps, planning, and helping motivate those around him/her in order to propel the group along a unified vision/mission
