Judges have discovered the Internet’s 600 legal blogs, citing them at least 32 times in 27 decisions over the last two years.

A blog, short for Web log, is a Web page that acts as a continuous journal of the writer’s commentary, news and links to related sites. Blogs began, often as personal diaries, in the 1990s but came into their own in recent years among lawyers who use them to share with peers the latest developments in legal specialties.
