I use Google Docs for anything simple (1-3 pages), and if it has no citations or more than 2 figures. After that I upgrade to LaTeX.
I had a conference demand a docx file for the paper submission. I figured “fine it can’t be that bad to use word for a simple 8 page publication” but boy was I wrong! It was torture trying to get it formatted and arranged properly. Every part of the word tool is weird and clumsy.
Oh, and they’ve completely broken the original GUI WYSIWYG (what you see is what you get) premise of a GUI style editor. The PDF it creates often doesn’t look anything like what the document looks like on the screen.
I dropped a note on the conference organizers about the docx requirement. I don’t have that many hours to fuck around with bad tools so I can attend your venue. I’ll just go to a conference that doesn’t torture us to participate.
