The World According to Twitter

Once there was slow talk and silence. Then came letters - delivered by horse or sailing ship, months in coming, deep in thought. Then came the telegraph, telephone, cell-phone, e-mail, Palm Pilot, Blackberry, texting, instant messaging, and now — Twitter.

Non-stop, instant communication from anywhere, all the time. Hyper-connectivity, always present, in a non-stop global mind-share of twittering micro-thoughts. "Hungry!" "Love duck." "Doing dishes." "Off to bed."

We're pushing deeper into the seamless cyber-mind. Are we happy now?

This hour On Point: Twitter, and the hyper-connected culture.
