Why was this downvoted? This is clearly true. I am in fact doing it right now. I am sitting in an airport and clicked around 20 different comment sections and articles from HN so that I could read them later. None of them gave any issues. The only js that I decided to allow was from HN so that I could expand/hide comments.
Does this mean that all websites work? Of course not. But this allows the user to choose which sites to allow to run js. I'm not going to pretend that this is an easy task for non-technical users, but we should be promoting these kinds of habits, not scoffing at them. We should educate as many users as possible that they can still (for now) control much of the web-based code executing on their machines.
