BEST CAREER MOVE Alberto Ibargüen He may have been sincere in telling his colleagues at the Miami Herald Publishing Company -- from reporters to advertising reps to pressroom workers and anonymous midlevel managers -- that he will miss them greatly. But in fact he couldn't be happier. No longer struggling with a whittled-down, anemic version of a once-proud newspaper under the life-sucking, soul-crushing financial thumb of parent company Knight Ridder and its pinhead CEO Tony Ridder, 61-year-old Ibargüen snagged what must be one of the best jobs in the land -- president of the John S. and James L. Knight Foundation. There he'll be facing a very different, and much more appealing, challenge: how best to dole out some $90 million each year in grants to improve journalism and strengthen the social fabric in communities across the nation.
