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.
I still find it funny that Twitter was initially meant to be used though SMS messaging. Twitter’s roots in SMS defined its success in many ways; things like the 140 character limit.1
1 SMS messages can be up to 160 characters in length. Twitter tweet character limit is 140 because it left 20 free to write the target username (for a DM) in the text message.
