Typeset is a new Javascript tool that can make any website worthy of Gutenberg. (Not Steve.)
Good typography on the web is pretty rare, because it's hard. Consider quotes. Books use smart quotes, or quotation marks that mirror each other both horizontally and vertically on either side of the term being quoted. They just look nicer, but we don't really use them on the web, because they require you to memorize obscure keyboard commands to insert. Or how about the em-dash? Online, we substitute double dashes (- -), but properly, they look like this (—). A proper em-dash looks better, so why don't we use them?
