The Washington Post's Ellen McCarthy wrote a great piece on Larry King's Twitter account and how the 81-year-old broadcast legend reaches his 2.55 million followers. But perhaps the best insight in the story is the exact old-school-yet-innovative method King uses to tweet:

"I Twitter everyday," he says in his hotel room at the Ritz-Carlton in Washington, where he was staying in advance of a Wednesday night appearance at the Newseum.

When Larry King wants to tweet, he doesn't log onto the Internet. He pops open the flip phone stored in the shirt pocket between his suspender straps and calls the number for a voicemail set up specifically for this purpose. Then he dictates a thought that will be picked up by an assistant and transcribed onto his @KingsThings Twitter account. And nearly 2.6 million followers are there to receive it.
