Freedom.

Not that he needs my link to draw an audience, but you ought to read what Frank Rich writes today in the New York Times about freedom and speech in America since 2001. Short version: we're fighting for freedom in the Middle East and around the world, but our freedoms at home are under attack as never before. At a time when even bloggers are being warned to "watch what you say," we're well advised to, like Mr. Rich, exercise our rights. Use 'em or lose 'em.
