Pfft, you call that an emacs-HN integration? Something tells me you had
to bring in the browser at some point, either when reading this message,
or writing your reply. I am using nnhackernews. Now that's a real
emacs-HN integration.
Sure, that's just another package I forgot existed. Guess what? You can still use all of them together in the same instance of Emacs and they probably wouldn't even complain about it.
