The Union-Tribune finally got around to announcing how many people it's laying off. The number is 112, not the 200 that had been posted yesterday.

The U-T says it will focus more on local community news and launch what it calls a ''micro-zoning'' initiative for small businesses to advertise at lower rates.(E&P)
