I have written a similar blogpost on writing here [0], which was received well by HN community. I'd also recommend the book "Style: Toward Clarity and Grace" and this document [1]. These resources tremendously helped me to improve my writing.
The link to [1] appears to be a subset of a larger document/program from University of Chicago (but this appears to be source from OSU). Do you have a link to all the book/materials? Thanks
