Since the first time I saw the part of that statement with regards to style and voice it's been eating away at me. Because in my mind, I don't think that's entirely correct.
Yes, a blog will show whether or not I can string two sentences together and have a grasp of basic grammar. It will also show if I can be entertaining or even amusing, but not what my books are like.
A blog is about sharing and creating conversations. Sometimes it's even about imparting wisdom or lesson's learned. Yet it's not really a story or novel. Yes, both entertain, both should have a beginning, middle, and end, but not in the same ways. My voice is totally different in my blog posts than it is in my stories. And even between stories, my voice can vary depending on the genre and POV. So how could a reader know what my books would be like by just reading my blog posts?
I do feel blogs can bring us closer to readers and other writers, as through them we get to know one another and can connect. And, if they like me enough through the blog, they might go ahead and click on over to the website and check out my books. There the sample chapters would do the job of showing my actual writing voice and whether or not it was one that appealed to them. But it would be a side effect of the blogging, not something the readers would have known about until they went the extra step and clicked over to the website.
Am I full of it? What's your take on this? Convince me! Let's discuss. :)
