I see 3 schools of thought:
1) HN should be more mobile-friendly, so I can read it.
2) HN should be more of a platform on top of which users can build tools to use it, so let's build one.
3) Why not both?
I think both iOS and Android have already a plethora of user-made apps. (some of them ok, some of them not ok)
On a tablet i prefer the HN website to any of the apps currently available. On a phone, I think there are a few good Android apps and no good enough iOS apps...
What is the best HN experience on mobile? I think there's need for better understanding of what we "want" from mobile, apart from the obvious things (i.e. readability)
