It's a special journalistic edition of Mailbag Friday! Today's question comes from Molly Eichel, assistant editor at Philadelphia City Paper:

I was hoping you could help me out with a linguistic conundrum. I work at the Philadelphia City Paper and I wrote a blog post about the inclusion of the word meh into the upcoming edition of the Collins English Dictionary. I think meh doesn't deserve a spot in a reference book; it's slang at best and sound effect at worst. A blogger at Philadelphia Weekly disagrees. I would really like to hear your thoughts on the matter, so it becomes a legitimate discussion rather than a spat between two bloggers. What do you think about meh's inclusion into a dictionary?
