Mozilla FireFucks

What's not to hate about Word? It crashes alot, it bloats documents (a simple 20k HTML file becomes 80k), none of it's document views or previews is really WYSIWYG, so I get to try to read black on black, it makes it hard to do simple things (like a simple sieries of bulleted lines, or adjusting text offsets), when you get into any construct that is remotely complicated you often hit backspace once too many and oops--the document gets into a strange unfixable state--undo or redo from scratch, it makes itself the default program for editing HTML but doesn't understand it, you can't see the beginnings and ends of format modifiers and/or it doesn't place them where you tell it to at line breaks, etc.

I used to use Word Perfect, until it turned into a Word clone. I'm not anti-Microsoft; the rest of the Office suite is wonderful and I'm very pro-IE, but MS Word is the worst program for writing documents ever.
