It even uses Brandon Sanderson. I like Brandon Sanderson. I like his stories. You may not care about writing, and that's fair enough, but for people who do it's fairly clear that his style has some weaknesses. I don't condemn him for that. I also don't see why he shouldn't try to continue improving it (as he generally has over time so far, though recently he seems to have settled in a bit more).

Anyway, hit the link below. It goes to a blog entry I made last year, which talks about basic dialogue strategies and uses an exchange from Sanderson's Mistborn as an example of one thing to avoid. The specific example is under the "He Said, She Said" section of this article.

My blog also has several other entries that talk about basic writing and storytelling, with examples, if anyone is interested in browsing through it.
