I'm as guilty of oversharing as the kids of today I purport to hate so much. I tweet, Foursquare, Instagram, Facebook.... I even GetGlue. If it's not basic narcissism, then I don't know what the psychology behind it is, for me or the current generation of check-inners. Or, checkers-in.
Here's a thought, though. I'm a lost cause, but the current generation; let's call them Gen Text - what if all the sharing and checking in is a *good* thing? As a parent, I rather like the idea that, when my kids are old enough to be out and about on their own and with friends, all I have to do is check my own smartphone or their Twitter feeds to be able to see where they are and who they are with. In real time with GPS, potentially. What if the things they share as kids; pictures, videos, songs, playlists.... what if, when Gen Text is my age (or younger), this desire to share translates into sharing other things for free? Wealth, knowledge, experience. The kids of today are extremely technically proficient, a field which is growing, not shrinking. A field where there is the potential to make a lot of money.
"Billy has checked in to Joe's Cafe" and he posts a picture of him feeding three homeless guys.
Gen Text is often criticised for being narcissistic and shallow, and that may always be the case, but if Billy wants a retweet for something like that, and if it means his parents know he's safe, I'll deal with a little mirror-gazing.
Something to think about.
