An excellent article about writing, which is accessible at Scribd (youtube for docs).
A Scandinavian professor has told me an interesting story. The first English manuscript prepared by one of his PhD students had been written in a personal style, slightly verbose but with a humoristic tone and thoughtful side-tracks. There was absolutely no chance, however, that it would meet the strict demands of brevity, clarity and impersonality of a standard article. With great difficulty, this student eventually learned the standard style of producing technical, boring and impersonal scientific writing, thus enabling him to write and defend his thesis successfully (Fig. 1).
