Suggestion: Add the subdomain when it is different from www
This morning I nearly had a heart attack when I read the title 'Good bye, Google Maps… thanks for all the fish' from 'google.com'. Thankfully I was too soon out of deep sleep to have a physiological reaction... It certainly woke me up though!
Afterwards I did ponder why it was showing google.com domain, and yes, I can understand it can be misleading.
