Two weeks ago I had a talk with Alex & Berto, two emacs gurus here in Igalia, about fast editing with old and new editors. They introduced me some basic emacs commands while highlighting some emacs' awesome possibilities in coding. Really an amazing editor!
My limited experience in emacs don't let me cook bacon & egss with this editor (yet!) but I got to customize my .emacs for quick blogging adding only two lines. Now, I can blog up a post while editing/coding easily.
To blog with emacs you only need a weblog supporting xml-rpc (WordPress rocks!) and this lisp package. Notice you can need some extra packages matching mt.el's dependencies too but all information is self-contained in mt.el (installation, customization, requirements, etc.)
ohppss! ... I almost forgot to say this post was blogged in emacs :)
