considering the fact each one of the three of us hates the others -- "hate" is a strong word, and it certainly can't apply to someone you wouldn't even recognize on the street, but we'll let that technicality pass here -- getting all three of us to agree that you are wrong, well, that constitutes a major achievement, to be sure.
Well, hey, if I can do anything to ever get any of you guys together in a way that actually makes a positive contribution to real-world PG customers, then all the insults you have flung my way will have been worth it! Again, anyone else still listening to this thread (god help you) can easily check out the veracity of the various claims and the counter-claims simply by trying out the files in question on their honest-to-god reader devices. You don't have to take BB's words -- or mine -- on this matter. z-m-l.com vs. gutenberg.org -- go check it out for yourself! Personally, I don't think even IF BB's stuff made a theoretical contribution it would matter. For the simple reason that PG contributors do not want to use yet-another custom PG file format. If contributors want to submit in ZML or Marcello-L then let them -- as long as you let the rest of us fix what ends up busted in the other file formats -- so that customers with HTML, EPUB, or MOBI devices can actually read and enjoy that PG contribution, rather than have their experience of some fine author intruded-upon by the technical politics and/or favorites of one or another PG contributor.
