I tend to prefer http://hckrnews.com just because of the more intuitive browsing interface and filtering options (top 10, top 20, etc). I have it as a shortcut on my main phone screen and bookmarked in all browsers.
Ironically, for me typing n is indeed HN, but the next one is nbcolympics.com, (and we all know how useful the latter is if you don't have cable subscription...) so I assume I don't need to check my self into a HN addict clinic just yet
