I use it 95% on mobile and rarely curse the UI.

I like that it renders quickly, shows lots of articles, and shows lots of comments.

It takes concentration to vote and hide links, but I think it’s optimized for reading and commenting. Better than any other forum, I think.

The performance is awesome, but the UX is rather bad.

Everything is tiny.

Everything is tiny, but it doesn't pointlessly restrict pinch to zoom. Thus interacting is more of a 2-finger process, but so what? It's refreshing for a site to optimize for reading instead of chasing maximum engagement.
