As the article stands, a reader would come away from it with the assurance that the diminished fourth is a diatonic interval. (Read, checking for occurrences of the word diatonic.) Is this a good idea? In two senses the interval is diatonic, but in other senses it is not (see Diatonic and chromatic). Perhaps this needs some work.
