If 140 chars isn't enough

  It seems 140-characters is not enough for Twitter's advertisers.
  This is not something I had thought of. It's quite creative. And it suggests how Twitter might use its position as the system software vendor to tilt the table in favor of its own news service. Their news alerts would not be limited. Yours would.
  I'm tellin ya, it's long past time to be working on an independent medium for transmission of tweet-size bits.
