"The internet is more public than many of us think"
It's more public than anything ever.
The 1953 coronation of the current Queen was watched by over 20 million people; LiveAid in 1985 had an estimated audience of 1.9bn. But they were still only seen by people in countries where these were broadcast, who happened to sit in front of their tellies during the time of the broadcast.
Your Facebook update of "Just had a shit" or "Sunita Singh smells," is published to approx 2.1 bn potential readers right this minute, and could be around for decades more. And it's all searchable on demand: no longer blink-and-you-miss-it.
We actually don't know what this total-information world is going to be like, because none of us have ever lived there. But we're slowly finding out: it's certainly interesting.
Meself, I reckon there's a lot to be said for an elegantly bound, crisp-paged, old-fashioned diary, with a little lock and key and "Keep Out" scrawled on the front, hidden under your pillow. Yes, write about your crap day and your evil thoughts about your colleagues. Just don't fucking publish it.
