I came across this article today and thought it was intriguing. While this doesn't talk about novel writing in specific, I still thought it was worth the read.
I especially like their first two pieces of advice: Writer shorter and shorten your sentences.
While variety in sentence structure is important, I think it's worthwhile to recognize the importance of writing concisely.
I also thought that their advice to avoid jargon was also useful. Jargon is everywhere. The avid sports fanatic might know terms that other would not, and the list goes on.
What do you guys think?
