Kevin,

I am not sure this is a big conspiracy. I confess that of my 10 or so pictures that some of them are 3-5 years old and some are very recent. I don't have a constant supply of recent pictures of me.  I usually take pictures of places and of my friends, not myself.  I think in life some people are just more attracted to taking photos, especially of themselves in a particular place.  I agree that not all photos should be older. But at the same time, I think that pictures that look like a models shoot  don't represent reality either. If we really want reality, then we all should post pictures when we first wake up in the morning. This is reality.  

Like others have said. The cam doesn't lie.
