Social media is about stories, and what's more interesting - to you at least - than telling your own?
When you post, you're building a narrative: this is who I am and this is what I like.
You're creating your very own movie, pulling in a range of characters. Then you've got stage sets and let's not forget the bit parts; those people who dip in and out of your life and provide endless story fodder.

We hear from the unwitting extras: from the seat mates on a plane caught in a publicity storm after a woman posted about the apparent beginning of their great romance, to a man who helped his neighbour and ended the subject of her tweets.

Aleks Krotoski explores the tension between entitlement and a feeling of voicelessness.
