Take Twitter. If you think a thing, and it might have the slightest amount of controversy, maybe you'd better think twice before you post it on Twitter. PARTICULARLY if you're a celebrity.
The internet when it started is not the animal it is today. When it started, everyone was stationed at a computer, in their office or at home and not everyone had one of those. I can remember in 1997 sneaking into my employer's company showroom, because the computer in there had the internet. I'd never been on the internet before. I kept my eye open for any witnesses while surreptitiously getting onto the internet. Can't really say the experience was overwhelming, but a few years later, I had the internet in my own living room - with a noisy, dial up modem - even then didn't really dare to do as much as I wanted to because of the ever increasing telephone bill. But by then, most people had email, and that was already an advancement. Now, instead of having to hand write a letter to your friend in America, you could type up and send an email.
