right.

I'm gonna stretch my metaphor a lot.

Imagine street signs use polarized glasses (or something, I'm not an optics). I can see only those signs whose glasses I where.

I choose to wear google glasses. Everyone does, the competition is pretty good but google has been around for so long that I just don't really bother with anything else.

Now google takes down some signs. Am I really going to carry 3 pairs of glasses (N pairs, M are relevant) in order to figure out what street I'm on? or am I just going to walk a block to the next street and use the service google hasn't arbitrarily decided to destroy.
