The "velocity of life" seems to have gotten to a point where everything moves so fast that if we even blink, we miss something. So lots of stuff gets regurgitated over and over... and in many cases we don't even notice.
I think about what I write here (and I do write a LOT of original material) and realize that I could send an article out at eight in the morning and the exact same article again at eight in the evening... and a completely different audience would see it.
Maybe I'm not as "optimistic" as I am just realistically resigned to this being "reality" as it stands right now.
