Increasingly, I'm inspired by entrepreneurs who run nonprofit organizations that fund themselves, or for-profit organizations that achieve social missions while turning a profit.

It's fine to have social media that connects us with old friends, but we need tools that help us discover new people as well.

I can imagine Iceland becoming a good place to run a controversial Web site. But... Iceland may find itself forced to defend controversial speech.

If I use Facebook to stay in touch with my high school friends who are church-going Republicans, I may be getting more ideological diversity than in hanging out with secular progressives on the World Politics sub-reddit.

When you sign up for Facebook, the service first searches for any mentions of your name and suggests you befriend anyone who has mentioned you in their posts. It then asks to access your e-mail account so you can connect with anyone with whom you regularly correspond.

You can't believe the number of non-profit organizations (around Whitefish). There're hundreds.
