What do we talk about when we talk about poetry? Punctuation conventions. Last night, at the Great Emdash Colloquium Synod of 2010, otherwise known as the proofreading party, the following resolutions were approved:

1) Two hyphens does not equal one emdash. (Sigh.)
2) The use of spaces before and after emdashes is a matter of style*.

If you have other resolutions to submit to the council, please do so at this time.

*over substance.
