Blogs, short for Web logs, are personal online journals. Individuals post them on Web sites to report or comment on news especially, but also on their personal lives or most any subject.
Some blogs are whimsical and deal with "soft" subjects. Others, though, are cutting edge in delivering information and opinion.
As a result, some analysts say U.S. intelligence and law enforcement officials might be starting to track blogs for important bits of information. This interest is a sign of how far Web media such as blogs have come in reshaping the data-collection habits of intelligence professionals and others, even with the knowledge that the accuracy of what's reported in some blogs is questionable.
Still, a panel of folks who work in the U.S. intelligence field - some of them spies or former spies - discussed this month at a conference in Washington the idea of tracking blogs."
