On Writing Well by William Zinsser http://www.amazon.com/Writing-Well-30th-Anniversary-Edition/dp/0060891548 http://www.amazon.com/Writing-Well-30th-Anniversary-Edition/... It's absolutely the best book for anybody who keeps a blog or writes any sort of non-fiction. I try and re-read it once a year.
