I use MiniHack, which is mind-blowingly good now that the update came through. Full comment posting on mobile and tablet, upvoting, flagging, everything.
Agree, but the current version omits all numerical point data and the repeating #comments 30 times uses alot of pixel space. I'm wondering if there's not a hack or abstraction that might benefit the layout.
That website doesn't have the same thread ordering as the homepage on the real thing, or it seems to be delayed... if you pull up both in parallel you'll see it quite obviously...
I currently use this site for hn mobile: http://cheeaun.github.io/hackerweb/
