I've added it to the home screen. It's fantastic apart from 2 issues (iOS):
1. Swapping between comments and the article (like 5 times) and then wanting to get back to the main page. (I have to hit back the same amount of times as I swapped.)
2. When clicking a link, there is no way to get back to the main page. (is there a way to get the status bar back when browsing via homescreen?)
