If the project was lucky enough to have a writer or two well-informed about some specialized subject, and if their work was not degraded in quality by the majority of people, whose knowledge of the subject is based on paragraphs in books and mere mentions in college classes, then there might be a good, credible article on that specialized subject. Otherwise, there will be no article at all, a very amateurish-sounding article, or an article that looks like it might once have been pretty good, but which has been hacked to bits by hoi polloi.
