having discovered the existence of this thing called mdash—and mastered how to use it—I am now having second thoughts.

given the narrow width of most e-book readers, there is an arguable case for revered to the - simpler - style of hyphen with spaces, as the line breaks are then less of a challenge to e-reader firmware.

kindle will not line break on either side of an mdash, so it resorts to breaking one word earlier in the sentence, which can lead to very short lines / ugly page layouts before / after the mdash construction.

what do others think & prefer ? is this another case when e-books and printed books style conventions may diverge in time.

maybe technically a soft break character can be placed alongside emdash or ndash but that seems like technical overkill ?
