Last week marked the first week on the job of the Chronicle's new publisher, Frank Vega. Now you may be wondering to yourself (or not) who is Frank Vega? A good question, actually, as it turns out Frank is a bit of a notorious character. He is, depending on how you look at it, either a bold, tough, visionary CEO with a knack for trimming fat or a ruthless, tyrannical union buster out to do nothing but keep down the down-trodden. Either way, the hiring of somebody with the nickname "Darth Vega" as publisher is a curious choice.
