Do you use Twitter?

Or do you laugh at those of us who do?

Let me give you just one example of the value of Twitter. Yesterday, I read Andrew Ross Sorkin's column in the New York Times and tweeted to him:

@andrewrsorkin How about Yahoo's Marissa Mayer for CEO of the Year?

And, two minutes later, he answered:

@BoringOldWhtGuy her stock is up but a huge part of that is the result of the increase in alibaba's valuation

Now, I ask you, where else can you leave a comment, or ask a question, and get a response so quickly (or at all)? Try doing that with a letter to the editor or by leaving a comment in the comments section after a piece.
