I'm going to post this as a top-level comment rather than an answer, so that nobody feels under attack. I don't know Kovid other than from being a Calibre user and from reading about him (mostly here on HN). But I do find many of the posts in this discussion, way more insulting and close minded than anything I have read written by him.
