The site is a social MEDIA site, not a networking site. You post whatever it is you want to share with friends and family. Pictures, video, words....you share your media with others you trust.

If you want a networking site, I'd suggest LinkedIn. That's where you can network, build business connections, what have you.

You want social networking? Walk out your door and talk to whomever you feel like talking to. THAT'S social networking. Face to face interaction.
