I Tweet then i exist - You're only alive if you're on Twitter. If you're not there,

You're only alive if you're on Twitter. If you're not there, you're not living.

@james: 'You're not alive. You're just a person who doesn't tweet.'

@alex: 'I'm alive. You? You're dead. I checked your timeline.'

@sophia: 'If you don't tweet, you're not living. You're just existing.'
