There's a lot of other things Discourse threads have (media, collapsing, proper markdown, editing toolbars etc.).

  HN has collapsable threads and uses tables for layout, which aren't exactly efficient markdown, so makes the opposite point you're trying to make. Namely, even with bloody awful markdown, HN still delivers 1000 comments in 1/4 of the bytes. Another interesting idea, as almost everyone doesn't actually comment, wouldn't it make more sense to load the editor javascript dynamically? As far as I know, the silent majority read comments but never reply. In fact, I vaguely remember Jeff even having a blog post that most people never participate, they just consume (could be wrong!). Also, I haven't kept up with it, but mobile browsers used to have fairly aggressive cache invalidation to save space on the phone, so serving big chunks of JavaScript in the hope it might get reused one day wasn't actually a great idea.

    > Namely, even with bloody awful markdown, HN still delivers 1000 comments in 1/4 of the bytes. Are you sure this is correct? I count 700kb of total content (including the actual HTML and CSS), not 4mb, so I think your comments are premised on a number that's off by almost 6X? http://imgur.com/a/gPiEb http://imgur.com/a/gPiEb

      Sorry! Was just repeating a number further up the thread, should have checked myself. Worse still, you'd already corrected him and I didn't notice :(
