Hacker News itself is a good example — no JavaScript bloat, loads instantly, works on anything. I also appreciate sites where you can actually find what you came for without dismissing three popups and a newsletter signup first. As someone who came late to the internet and learned a lot from straightforward, no-frills documentation sites, I have a soft spot for anything that just gets out of the way. With that being said, It ISN"T the most eye candy friendly site. But I guess that's exactly the attraction.
Ever since my phone's wifi broke and I'm on 1 bar LTE at home, I've been using HN more. The site even looks good and modern imo.
