It is almost identical to 'Combinator', another WP HN app. No login, posting or replying functionality... which is why I'm writing this from my android phone! I do appreciate the cleaner typography and the links in comment actually work (combinator doesn't fix links). It's good, but not as complete as what is available on Android.

Taking a bold dive into the depths of despair that is HN's Microsoft-friendly sub-community. Kudos, good sir, I applaud you!
