Paul Bradshaw defines Twitter in an interview… via Twitter.

The post starts in German, but Paul’s bit is in English:

halbluchs: @paulbradshaw what makes twitter so popular and addictive? is it just a hype or is it more?

paulbradshaw: @halbluchs the same things that have made texting so popular: brevity, connectivity, control.

Worth a read, especially for journos who are trying to figure out the best way to use Twitter in their jobs.
