Update on "After I post it here, does it exist on the internet?"

The answer is no, it does not exist on the internet.  

After I post it here, does it exist on the internet?

Of course it does, since you are looking at it.  But to all the search engines, it does not exist.

It's like a quantum physics thing.  I archived it, so even if this blog goes away, it exist on the internet.  Even when nobody can find it.
