A pertinent tale told on the BBC site in a post titled 'Park and write': it tells of a homeless woman who although unnoticed by those around her has made herself known through blogging and the info-sphere - an odd type of co-presence?
"A homeless woman in London has been living in a car since last summer. But by writing a blog she has put herself in touch with an international audience.
It's a tale of our time - about being cut off from everything around you but still connected to people thousands of miles away.
A woman becomes homeless, so she gets into her car and drives. Except she has nowhere to go - so she stays in the car, with all her possessions heaped in the back, sleeping in the front seats, parking in secluded streets.
For eight months, no one notices her, because she makes sure she looks respectable, taking showers and even ironing her clothes in public places like hospitals. She has made herself invisible, out of touch from anyone she used to know - and keeping separate from other homeless people.
But this is the information age. And even though she doesn't speak to anyone, she can go into a library where she can access the internet and write an online journal - a homelessness blog - which she uses to describe all her unspoken experiences and feelings."
