There's An Entire Universe In

Twitter Was Around Communication And Visualizing What Was Happening In The World In Real-time. Square Was Allowing Everyone To Accept The Form Of Payment People Have In Their Pocket Today, Which Is A Credit Card.

I'm Less Interested In How People Are Following Each Other And More Interested In How They Are Following Topics And Tweets Themselves. People Are Following More Key Words And Concepts And More Ideas And Acting On Those Rather Than Individuals Or Organizations.

I Loved Couriers. You Had This Transfer Of Physical Information Happening Throughout The City And The World. Someone Picking Up The Package, Putting It In A Bag, Going Somewhere, Taking It Out Of The Bag, Giving It To Someone Else. I Thought That Was So Cool. I Wanted To Map It, To See That Flow On A Big Screen.

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.

It's A Matter Of Invitations Versus Context. Twitter Is Really Good At Providing Context, Like, I''m Having Coffee At Third Rail Coffee.' Foursquare Is About Invitations To Places. In This Respect Foursquare Has Started To Replace Yelp For Me.
