Weekly Review: Would You Like That With or Without the Space?
This is where this post title gets it’s name. Whether or not an em dash is to be used with spaces or without seems more a matter of preference. Personal if you are writing for your own blog, organizational if you write for a publication of some sort.
Something I have been interested in, too, especially since Kirk Lennon at Newsvine critiqued my double-hyphens. (Thanks, Kirk.)
Personally, I prefer the em dash with a space rather than without, but I have no real basis for making that preference.
