Excerpt:

“More recently, “begs the question” has been used as a synonym for “invites the question” or “raises the question”, or to indicate that “the question really ought to be addressed”. In this usage, “the question” is stated in the next phrase. For example: “This year’s budget deficit is half a trillion dollars. This begs the question: how are we ever going to balance the budget?” This usage is often sharply criticized by proponents of the traditional meaning, but it has nonetheless come into common use as a result of its use in the media, especially by people ignorant of its original use. Argument over whether this usage should be considered incorrect is an example of the debate between linguistic prescription and description.”

..well then. What DOES it mean?
