I recently endured substantial frustration trying to save a slide show as PDF (never achieving anything acceptible), but generally I have had decent luck with regular notebooks (even big ones). Here, "decent luck" means "allowing for the inability to float figures and tables, the inability to interact with BibTeX databases to produce inline citations, etc".) Now Paul Romer claims Mma's limited PDF support must be intentional and describes his own reasons for believing this. The idea seems to be that Wolfram does know how to use Mma to produce good looking PDF documents (see NKS, for example) but is refusing to share that knowledge in order to promote its proprietary CDF format. My own view is that there is no conspiracy of silence; rather Wolfram has sadly limited interest in supporting the production of beautiful printed documents (except his own, as NKS evinces). Romer's "evidence" is too impressionistic -- it seems more of a lashing out in frustration. Is there any real evidence for his view (or mine)? And as a related question, is there any active Wolfram project to turn Mma into a more serious academic authoring tool?
