I think that a long discussion about how portable devices, equipped with quick access to social media, have changed many people's lives, imo, not for the better, would be a good discussion
Alone, the instances of car deaths due to texting while driving is pretty damned scary.
And the number of extra-marital affairs / declarations of divorce, etc, that happen over social media, is pretty damned astounding.
It's as if people think that portable devices have the answers to life's questions in them....
...and it's as if people throw common sense completely out the window when they are dealing with their portables.
Not to mention the legal ramifications of doing stuff that can, at some point in the future, be used in court proceedings for some reason.
