I've added Ymacs to do post editing on my blog. I love it! It really feels like having a mini version of Emacs running for editing blog posts.

I've set up Ymacs in html-mode, so that I get HTML tag completion while I am editing. I am also starting to think about more ways to integrate this with my blog.

There are a few issues, to do with Emacs key-commands conflicting with browser and Mac OS/X shortcuts. For example; pasting in Emacs is control+y, but in Ymacs you need to type control+shift+y.
