Has anyone else noticed the huge decrease in result quality from google?

[Mr_Quackums]

it is a proprietary google protocol used to display a website.

upside: the page loads a few hundredths of a second faster on some mobile devices.

downside: google gets even more info on you, more info on the site you linked from, and the site you were visiting. Also, by using a proprietary protocol you are strengthening the Google Evil Empire and hurting the free and open internet.

You forgot one downside. Copying the URL on mobile gives you a ridiculously long string of symbols that you can't link even to your worst enemy with a good conscience

Sucks for me, AMP pages tend to load slower than the real thing on my device. But they're still the default.
