Something recently reminded me of Paul McHenry Roberts's How to Say Nothing in 500 Words.

It was written mostly for high school children, but it has lots of solid advice and its primary focus is something crucial: making your writing more interesting to read, aside from writing style.

The sections, "AVOID THE OBVIOUS CONTENT, "TAKE THE LESS USUAL SIDE", and "GET RID OF OBVIOUS PADDING" are most likely useless or groan-worthy obvious to anyone who's at all likely to read this comment. The only section I think is particularly likely to be relevant to rationality writers is "CALL A FOOL A FOOL".

Still, it's a pretty entertaining essay, worth reading in full unless you're really that fucking busy like Luke Muehlhauser is.

The best idea in the whole essay is,

Those sentences that come to you whole, or in two or three doughy lumps, are sure to be bad sentences. They are no creation of yours but pieces of common thought floating in the community soup.
