We are a very open, very democratic site, which means we get all sorts of people. We do get some bad guys who are a few fries short of a Happy Meal. So we have to enlist the aid of our community to help us. The lesson implicit in this is that people will help you out and behave in a really good way. If you trust them, they will respond to that trust.

I had one simple idea about telling friends about arts and technology events. People in the community suggested everything else to us, and that's our theme. We're really run by the people who use the site. We just run the infrastructure, and help out with problems.

Choose your mistakes carefully.

Finding a good cause is incredibly hard and time-consuming.

I feel that one of the best things a person can do for another is to create a job. So you do OK commercially, and then you try to make a difference of some sort.

Treat people like you want to be treated; live and let live; and also give the other person a break now and then.

Getting out of the way is really important.
