The key advantage of the Internet over radio or TV is immediacy. Stories fly straight from pocket-sized devices to a great discussion in the sky with no friction being heard. Short bursts of information — as much or even less data than traders on the exchange floor use to make snap, million-dollar decisions — are what drive the conversation now.
Newspapers all have, or could have, vibrant web sites. Web sites are exciting because they are immediate, hamstrung only buy the stupidity of servers, how much traffic they can handle and how fast the Internet is working today. You share a story, and BOOM, there it is: Waiting to be discovered by random travelers, spotlighted by RSS, Tweets, Facebook updates and shared by a geometrical progression of friends you didn’t know you had.
The metaphor is: If you build it, they will come.
What is the metaphor for an app? Turns out it is exactly the same as the original newspaper paradigm: Here we are, come and get it.
