An interesting thing to consider in all this is the ultimate contradiction of pretty much everything we do.
Consider this: we are part of something that passes for "social media," yet we want privacy. By extension, what we're saying is we want to be seen but we also don't want to be seen, at the same time. Well, which is it?
Some of this is like the old conundrum of somebody saying they are "a little bit pregnant." No you're not! You either are, or you're not.
If you want privacy and you don't want to be seen, then don't participate in a public venue where your effectiveness depends on being seen!
Of course few people are willing to look directly at this, because they want their toast buttered on both sides.
