As a side note, from slide 49 on he talks about Google Maps embeds, and says if the designer removes the direct link from below the map you need to get the address, copy it, go to maps.google, paste it, search, find the right one, etc.
You do not need to do this. On the embedded Google Map you can just click the Google logo in the bottom left corner and be taken directly to a new maps.google page with the viewpoint centered exactly where the embedded map was. I even verified that it works on the map he was using.
TL;DR: Click the Google logo on an embedded map to view larger.
True, and it's even somewhat consistent behavior among embedded stuff (youtube, vimeo, etc.), but in my experience most "normal" people don't know that.
