More punctuation

I recently posted a great infographic about the ampersand. If you’re interested in punctuation, you’ll appreciate another article I found on 14 punctuation marks “you never knew existed”! My favourite is probably the interrobang, as I’ve discussed previously. But I also really like the guillemets (<< >>), which are used in non-English languages as quotation marks. The translation of “guillemets” is “Little Williams” by the way! Which is your favourite of the punctuation marks?
