I love dashes. Not this sort:
I liberally pepper my work w/them. While editing my manuscript, I've realized that I have a dash on every page. Every single page has anywhere from one to ten dashes. I don't know if that's a deal breaker as far as having a grammatically flawless ms(ha, ha...), but I definitely thought it showed a lack of variety. Some of those dashes could be semi-colons, or even plain ol' periods(so boring, sigh).
So I've been going through and deciding what dashes are absolutely necessary, and not just a product of my dash-feen. See! Geez, I can't get away from it! ;)
What about you all? Anything that you find yourself doing over and over again in your writing? I'd be interested to hear it!
