Men can comfortably claim credit for what they do as long as they don't veer into arrogance. For women, taking credit comes at a real social and professional cost.

But I really believe that when you give people authentic identity, which is what Facebook does, and you can be your real self and connect with real people online, things will change.

Real empathy is sometimes not insisting that it will be okay but acknowledging that it is not.

The social web can't exist until you are your real self online. I have to be me. You have to be you. Once we are online as ourselves, connected to each other and our other friends, then you can have the evolution of what becomes the social web.

It's pretty exciting to take real people living in the real world, their opinions, and have people have to react to that. As opposed to their perceptions of what people are thinking, which are often very different.
