His comments speak volumes, but don’t really answer the question.
“When I was in college I did a lot of stupid things and I don’t want to make an excuse for that … Some of the things that people accuse me of are true, some of them aren’t … There are pranks, IMs … I started building thie when I was around 19 years old and along the way a lot of stuff changed. We went from building a service in a dorm room to running a service that 500 million people use.”
The question, of course, is whether the “stupid things” in question will continue to come back to haunt him. When you’re now running a service with 500 million people, your earlier actions often times will weigh heavily on how people approach you.
