Let me add my ancient and quavering voice to the chorus. The problem is not that so few corrections are made. The problem is that so many bonehead errors are made. To be fair, journalists now have to deal with names from another alphabet, one without vowels. There really aren't any rules for transliteration from Arabic the English. That said, there is no excuse for the types of errors I see everyday. Rod Dreher, writing for the Dallas Morning News, claimed Pope Urban VII who died in September 1590, was involved in the controversy with Galileo. In the same article, he made Bjorn Lomberg a Swede. Since I live in Dallas, I am accustomed to the slipshod ways of our only daily and verify everything I read, which is how I found out that Urban VIII not the VII dealt with Galileo and that Lomberg is a political scientist/economist, not a scientist as Dreher had it. And that the man was born in Copenhagen, which makes him a Dane, not a Swede.
It used to be that papers like the Times, the Herald Tribune, etc., prided themselves on the fact that their copy boys knew things like that off the tops of their heads.
I suspect that papers would do better saving money on redesign and spending it on copy editors who can spell and will look up things they don't know.
