Perhaps, once so many people have so much stuff onlone, like those amusing-yet-embarassing drunken party pics, the rants about that shop down the road, the cringeworthy declarations of undying love to a suitor long-since forgotten...
Perthaps once that sort of stuff is on the 'net for pretty much everyone, then we will all collectively realise that pretty much everyone does stupid things at some point in their lives, and it will cease to be an important consideration, and we can all move on with life.
Perhaops uptight employers will stop gasping in horror when they discover a prospective employee got drunk at uni, and instead will realise that hey, that kid did pretty much the same as they woudl have done or did, and that was in the past.
A decade ago I was on usenet a lot, got involved in the opbligatory flame wars from time to time. It's all there, recorded forever.
I used to cringe when I came across them years later, hoping that people wouldn't see them.
Now I realise that the person who posted them, me a decade ago, isn't the same person as I am now; like everyone, I've changed as I got older; those posts were me then, this is me now, and if you are too dumb to appreciate the difference, then that's your problem and not mine.
The sooner we all realise that, the sooner we can all get on with ENJOYING LIFE!
