Again, I feel inspired by one of Kenrg's comments on one of my recent blogs, "Social Media: Are We All Frauds?", in which Ken concluded his comments with: It's not fraud or fakery. It's manners and common sense. And lessons we each need to learn the hard way for ourselves.
I generally agree with Ken, but tend to cringe at the concept of common sense, since it, in fact, doesn't truly exist. Common sense is a direct reflection of the family, society and culture in which each of us is raised - and because our individual experiences are unique, so is our idea of common sense.
Ken's excellent metaphor of the classic neighborhood pub, in which individuals tend to maintain a standard of behavior with the awareness that neighbors and work associates are nearby, immediately brings to mind the clueless semi-alcoholics who throw common sense out the window and let it all hang out - sometimes ruining the evening for everyone else.
The odd factor in social networks is the illusion, even if an individual is fully identified, that interaction is somehow anonymous - or that the same rules don't apply on Facebook as those in "real life". How much of what individuals share on Facebook would actually make the grade in a typical face-to-face chat with casual friends?
Of course, it's impossible to "block" someone in real life. But you can ignore them.
