That explains the many tests I just did with random copy and pasted articles. I just typed gibberish into the title. I mean, not all texts need to have a title.
EDIT it would be nice, from a UX POV, to request the title if it's missing, rather than silently deleting the story... also, you might emphasis the importance of it (because it doesn't seem important at all). Perhaps just labeling it as "headline" or "subject" instead of the generic "title" would help.
