Why didn't you go that route? There are so many phones and tablets out there now, you'd have accomplished almost as much public good with far less controversy.
Good question. Basically, it's not really the best way for people to browse this kind of stuff, and there are still lots of people without phones/tablets. You can get a much better picture of things with PM maximized on a 20" screen than you can with a 4" one. The phone is more of a backup for when you're on the road or in a pinch.
