For our zine, I much prefer MS Word, since we have to extract the text to format it for our site. Ideally, using an MS Word page size already congruent with web page sizing, usually around 6 x 9 trade paperback. Office paper 8.5 x 11 with longer lines, for poetry, means we'll have to edit the piece to fit the site. Copying / pasting from PDFs often ends up completely breaking the formatting and making more work. It's a nuisance.
