Perception and misperception

I'll admit it.  I'm a bit of a grammar snob.  Okay, more than a bit, but seriously people, if the first impression you're going to make on someone is through the written word, would you mind proofreading what you're sending out before you hit ?  The source of my ire this evening is a tweet from a popular provider of literary services, a tweet that suffered from a case of plural/apostrophe confusion.  I'm sure they're nice people, but I certainly wouldn't want my work edited by someone who gear's up for things.  

Snarking aside, there's a reason people suggest time and time and time again that your cover letter--whether for a poem, short story, article, book, or whatever--should be perfect.  This is the very first impression that people have of you and your work.  And, perception being what it is, we tend not only to favour first impressions, but also to hang on to negative first impressions.  Not what you want to be doing, especially if your intention is publication.  

So while a typo might be an oversight, the resulting misperception on the part of the reader about your grammatical prowess (and thus your overall writing abilities) is going to be difficult to change.  Take the time to carefully proofread everything you send out, otherwise you might find yourself the victim of misperception.
