Except that steve's menus are essentially ordered lists that need to be grouped and completed in a logical manner to achieve some desired outcome. Sounds like projects and actions to me.

Word processing isn't necessarily the same thing. Although, one might have a project to write an essay and break it down into actionable segments (e.g. write introduction, write section 1, etc.) with some first drafts or ideas drawn up in the notes field. Eventually, I imagine you'd want to move that over to a word processor or OmniOutliner, but it could at least begin in OmniFocus and be managed from there, and the essay document itself could be linked to OmniFocus project's note field

I'm all for the "multiple, specialized apps working in unison" approach so common in Unix-based systems, but I see no problem in using OmniFocus for tasks it excels at.
