I had one of those, goose bumps moments just now.

John Lennon would have been 70 today.

What might he have made of the world of engaging possibilities now?

Is it bringing people closer together? What might he have thought about tools that at the same time allow people to talk directly to loved ones across the world, yet also to be so cruel to each other through cyber bullying?

I think he was an optimist who might have been a fanatical tweeter.

How many followers would John Lennon have?
