Half-OT:

HN could optimize the layout for mobile a bit. I'm mostly reading on my smartphone and the links are all sooo small, I can barely hit them with my thumb.

I use http://hn.premii.com/ on mobile. No support for commenting but for just browsing is very nice IMO.

You could use Materialistic or any other apps that make it easier to view HN.
