I've been using semantic line breaks for a while for LaTeX since, using Vim, this is the only editing style that is sane on default settings. But that shouldn't necessarily be true; what can I do to make vim friendlier to work with files that are one-paragraph-per-line or similarly formatted? I'm not particularly concerned about version control just editing.
