this is an old horse chestnut but we are dealing with the ebook revolution here, with a totally new type of media with some possible unique features not possible with the printed word.
For example we all know the problem - and tedium of laying out dialog properly punctuated. when you have more than two interlocutors then formal punctuation is almost essential or the reader will rapidly get lost especially if it spans several pages.
SOOOOOOOOOO
I though why not give each character its own font sufficiently different to know whos speaking.
Is that a silly idea, has someone already done this
