Have any of the heavy users put together an emacs or conkeror stackoverflow mode that they'd wish to share? It'd be REALLY nice to compose posts and replies in a text editor rather than switching to the browser. Pages could load in the background while you get coding done, etc.
In terms of implementation -- I took a look at how stackoverflow renders in lynx and emacs-w3m, and most of the functionality is there (except for a few AJAXY things like upvote). So this should be very possible.
Alternatively, does anyone have any conkeror customizations to share? This might be the most unappreciated tool out there for the emacs aficionado. It's basically Firefox with Emacs keybindings, customized in .js files rather than .el files.
