Some of my friends have completely skipped creating an online identity. They just never really got around to it, and so never have.

Sometimes I think that was the correct choice to make. I don't think it was a 'choice' at the time, as in 'I don't want my details online' but rather 'I can't be bothered, there's nothing in it for me'. But now, having got this far, they now don't get caught up in the endless indexing and data sharing that happens without consent.
