WWB wouldn't exist if text had not routinely existed in
machine-readable form, thanks to word-processing. But the impetus for
WWB came from "style", not from troff.

Style was a spinoff of Lorinda Cherry's "parts", which assigned parts
of speech to the words of a document. Style provided a statistical
profile of the text: measures such as average word length: frequency
of passives, adjectives and compound sentences, reading level, etc.
WWB in turn offered writing advice based on such profiles.

Style was stimulated by Bill Vesterman, a professor of English at
Rutgers, who brought the idea to me. I introduced him to Lorinda, who
had it running in a couple of weeks. Then Nina McDonald at USG
conceived and packaged WWB as a distinct product, not just a
collection of entries in man 1.

Wikipedia reports a surmise that WWB sank out of sight because it was
not a standard part of Unix distributions.
