I'm a Capricorn, actually.

Twitter and Facebook are brilliant- tools, the journalistic uses of which are still being plumbed. They are great for disseminating interesting material. They are useful for gathering information, including from places that are inaccessible.

My dad was an engineer, and he became the CEO of Chevron. His was an engineer's mind-set: Everything's kind of a problem how do you approach the problem?

Everything is accessible to everyone all the time, and I think there are wondrous things to treasure with what the Internet has made available to journalists. But I think it's also had some effects that are less pleasant. It has chipped away at a sense of privacy and secrecy.

Liberation movements - operating surreptitiously and conspiratorially - thrive on discipline and suspicion, and punish deviation or dissent.

I make a joke that I'm the Internet curmudgeon, but 'wary' is a good way to put it.

Most recently, the president's reluctance to offend Senator Rick Santorum - a Catholic theocrat who believes that states should have the power to arrest gay lovers in their bedrooms, or even to criminalize couples who use contraceptives - was an occasion to wonder what, exactly, Mr. Bush was born-again into.
