I didn't downvote it but I imagine it's because your comment comes across as manic rambling. You managed to say "it will run in the browser" three times - once is enough. I'd recommend writing out your entire comment then deleting it an rewriting it to be more concise. No we don't expect literature in HN comments but good writing is a courtesy to your readers.
