self-importance

Lord Marchmont was about thirty years of age, and what is generally called a fine-looking man. His figure was good, as far as his height and proportion went; but his movements wanted ease, and, consequently, grace; and there was something of self-importance in his air—the last thing in the world to prepossess a beholder in his favour.

Wikileaks has always had a healthy sense of self-importance—one that seems, at least in part, well-deserved. But there's something uniquely hubristic about accusing a major newspaper (and former collaborator) of "gross negligence or malice" over the release of 251,000 unredacted top-secret cables—when the fault lies with the website itself.
