This panning of the Chicago Manual of Style is yet another reason to love the great Slate.

A teaser:

The final item of a list on the back cover, ("Incorporates recent changes in style, usage, and in computer technology") left a lone noun stuck between two prepositional phrases, and thus violated the vital, mind-toning principle of parallelism, which holds that items in a series should be phrased in equivalent form. Maybe the blunder should have come as no surprise.
