Your New Sunday Tribune?

[Commentary] When I describe the Tribune's top-secret project, everybody makes the same snarky comment.

The Tribune is designing a weekly edition that it will offer subscribers for a surcharge. The premium content will consist of long, thoughtful reporting and commentary-local in its focus-on the news and cultural affairs. The inevitable comment is this: That's what the Tribune is already supposed to be doing. Once upon a time perhaps it did. But the abbreviated coverage a diminished staff has been offering readers since Sam Zell took over has cleared out plenty of room for the Tribune to create a new product that's a quantum improvement. The Tribune is calling this new product by a rich and ancient name, Five Star-signifying the final edition, the one with the ball scores and theater reviews, the one a big city wakes up to in the morning. Sources tell me the Trib hopes to roll it out in January.
