I think you get into the apple in quote you referenced, understand vs think they understand looks like core problem with many non-trivial and often actually very well designed things. Another example of this kind I see too often is a CPAN to <choose-a-language> guy. He thinks he understand what it is ("That's simple! Just a bunch of libraries packed in tar.gz available via FTP and HTTP, right? Oh, and there is the search field to find them, yeah. We also have such thing in <our-language> - see, ftp://..."). edit: Another good example is a Trackpoint clearly.
