Re: Increasing engagement with Web App install banners - http://updates.html5rocks.com/2015...
"With respect, your arguments are not valid. It's fine though, you just wont be able to use this or newer features and I am happy for the users that it won't be offered on your site. With more and more advanced features we need to increase user trust and verifiability on the web, not decrease it. By not offering your site up on https there is no way to say that you are not being man-in-the-middle attacked and someone is injecting these advanced features in to your site." - Paul Kinlan
