I found this article more informative than Elements of Style. Elements of Style is full of poorly thought out grammatical "rules" which are flat out incorrect, or over-generalizations without much guidance on how to properly apply them, and even the authors of Elements of Style don't actually follow most of their own "rules." If you actually tried following Strunk and White's rules, your writing would come out sounding bizarre and stilted.
I love that book and find it both useful and actually funny. (It's meant to be in parts). But it is over prescribed. The forward clearly states that its original intent was to be remedial and correct college freshmen's bad habits. It isn't exhaustive. So I'm with you except for "Just".
