In a previous post I was getting at the issue of whether I should just do regular export or use latex "code blocks" for what I wanted in a final document. What I want is the ability to create a big, rambling, annotated org file -- with "keeper" stuff inside the latex babel blocks -- then tangle the .org file, thereby leaving all the annotations and lead-up notes behind. I'm sure I'm not alone in wanting "notes" to evolve into a "finished product" and orgmode would seem to offer a good path. So, I don't want to have to hand-edit out my so-called annotations. Is keeping the good stuff in latex babel blocks a best practice?
