Wow, this is actually very useable. It's actually super nice that it automatically uses my default editor for writing into textareas. Yay, using vim to comment on HN.

EDIT: For anyone else that wants to try this, it seems you need to open it with `w3m -cookie news.ycombinator.com` to be able to stay logged-in.

Also, as far as I know eww is now the main emacs ecosystem web browser. Works just as well as w3m and lynx do for me.
