It's an irrellevant annoyance that Google insists on using in [whatever Google Now Cards Are Called This Week] as far as I can tell.
Amp pages are so slow to load on my mobile that I can normally edit the amp out of the URL before the page has loaded and get to the proper site very quicky. And which inevitably works just fine anyway. And includes all the content as the site designer intended. (not always a good thing.)
Used to infuriate me but then some kind soul made https://addons.mozilla.org/en-GB/firefox/addon/amp2html/ and I can carry on blissfully unaware of amp for a bit longer.
Come on elReg, do the right thing and dump amp instead of just bitching about it.
