Well, I'm presuming newcomers are able to discern the difference between titles and mere taglines. Periodicals have titles scrawled across the top; tv shows announce the title after the opening sequence or at the end of the commercial for them. People can tell, as long as there's some familiarity with the basic medium. For a new medium like manga is to most Westerners, I can see them having no clue what's the title and what's just the storyline.
