I'm not sure where you go the idea that pseudo-celebs and IT managers are immune to stupidity or posting stupid articles. There's always an element of "who cares if my content sucks, lets just get it done" when posting bloggy stuff, and it's pretty apparent here.

Calling EXIF "back end stuff" is pretty stupid, I don't care if the author's ego is bigger than that statement, it's still true. The article might as well be how many apples fit in a bag or how long is a string.
