Between Twitter and Facebook, early word of mouth for a film can destroy it immediately or take something you've never heard of and make it a huge hit.
The minute you hear the word 'share,' you start thinking Twitter and Facebook. These are the places that people can very quickly share something they've just discovered.
I tell young people all the time, and now I'm telling anyone, no matter what your age: You can't take back the stuff you put out there on Twitter and Facebook, even e-mails.

Clearly there's value in Twitter and Facebook; otherwise, none of us would be involved in it.
I use Google+, and I find the quality of the comments are very sophisticated because there is more trust inside of Google+ than there is inside of Twitter and Facebook, for example.
The way the Facebook network is set up, it's not as suitable for content discovery. Twitter is better, but there are too many over-sharers.

I have a daily message, 'Stimumail,' which I use to stimulate the mind and heart. I have the opportunity to touch over 60,000 people I have never met. I also use Twitter and Facebook.
I said a long time ago that Foursquare can make cities better. You have these augmented realities like Foursquare and Twitter and Facebook that provide these virtual nodes and instant feedback from anywhere, adding annotation around a physical places.
