So Much I Don't Get

There is just so much I do not understand.
I don't understand how Google makes money on me writing this.
I am savvy enough to know that somewhere, somehow, somebody makes money for letting me send -- well, what? Blog-ese? And sending where? Cyber-Neverland? I guess so. I think so.
Maybe Blog-ese is just something in the air, virulent and free, like Bubonic Plague.
Regardless -- whether it's the Odyssey or the garbage -- I don't understand Whose reaping What for sending My Blogese into a Permanent Repository--somewhere.
So of course I don't understand how certain ads land on My Blogs. And I don't understand how you could ever effective filter them if the Reader's computer impacts the selection. How do I know what a reader's cookie are about?
Sheesh. Suffice it to say that there is  a tremendous amount I don't understand about cyber-advertising-networking-linking algorithms -- which is the best understanding I have of what Monetize does.
What I did come to understand clearly was this: There is no opting out, no sign-out button to click, no ctrl-alt-delete.Acceptance  came to me when the only opting-out program I could find contained 'jihad' in its name.
The single cyber-warning granted me from a younger generation old hand was, "Just remember, it's there forever. That's really the only thing."
Indeed.
I started slowly.  I get the New York Times online. I joined Huffington Post even word-a-day and watch the e-mails accumulate. Today I waded in. I read about Michelle Obama and what she wore to Haiti.
I looked at every photo.
There is just so much I don't understand.
