But a short article that may provide some insight (Same author):

The article is about how young people are more willing to discard personalities and start over. Their online self being someone that they care not to maintain, and if it becomes too tarnished, forget the password or are just 'over it', they can move on.
In real life, it's quite a lot harder to change.
Some of the old crusties (

) here have been doing the same thing for years. Wife, kids, house, job. Perhaps you have forgotten what it is like to change your life every few years , school, uni, moving out of home, first job, motorbike

.
Ie. The young in' who appear different from their online persona IRL is in fact a different person from who they were just a few months ago. But perhaps the personality of the screen name remains largely static as time goes on, fixed somewhat on who that person was when they first started using the (Or a) site.
