I've read this whole thread and guess I'm going to be in a minority here. I don't take exception when a post is written with errors, but I really get turned off when I read a story and find grammar/spelling/format mistakes that are of the kind to interrupt the flow of the tale.
I don't mean split infinitives and most dangling modifiers. I'm talking about fragments, a confusion between "then" and "than," faulty parallelism ... stuff that makes nonsense of an idea.
This isn't because I'm a snob. It's because I'm a writer and I take what I do seriously. I edit and revise and edit again whether I'm paid for the words or not. I check spelling and punctuation because I respect my reader and am flattered s/he would spend their time on my stuff. I want to make their time enjoyable and I want them to respect me and what I've written.
There are many ways to destroy credibility with the reader. One of the easiest is mechanical sloppiness. One of the easiest to avoid is mechanical sloppiness.
I have one chance to "sell" my words and ideas to the reader ... and I wouldn't show up on a sales call with my fly unzipped or in a dirty shirt. That kind of carelessness tells the "buyer" that I don't respect them. I want to flatter the reader so s/he knows that I care what s/he thinks and how s/he responds. So I check my spelling. I check my grammar. I check the formatting.
That doesn't mean that I don't make mistakes. Many slip by. But I've found that I can catch most of them by reading the story in reverse, one sentence at a time. I can catch them by reading paragraphs out of sequence. And I can catch them by sending them to my editor, a patient woman who goes ballistic when I do something stupid to disrupt my characters or logic. I edit hers for her, and she does mine for me.
It's the least I can do. If I only have time to do a quick draft and don't like it well enough to edit it, or don't have the time to edit it at the moment, then it goes in the files of stuff to be revised. I don't inflict it on a poor reader whose only sin has been to trust that I might have something mildly entertaining to offer.
Rabbit's pleas for editors is important. All writers, beginning or advanced or professional, need editors ... people who read and expect excellence. Those who are willing need to be taught new ways and have their errors highlighted. I know when I submit for the first time to the Library story boards I'll be grateful (though aggravated with myself) to have mistakes pointed out.
Many here have been willing to encourage new writers to keep with it and to show their efforts. I'll join in. It's important to try out the best you can do -- this is a great venue to get feedback in harmless ways. But you can make sure that people focus on your story, rather than on your mechanics, by taking care of it before you submit.
