Mark is NOT a role model. Millions of people get duped into sharing information they think will remain private every day. He has screwed over a lot of people in the process.

'Idea people' that hire 'tech people' don't get it. Lots of people have ideas for companies. The twins were not the first people to think of creating a friendster for colleges. They don't get to own 50% of another company because their company was delayed by a few months.
