In the age of the blog, who is a journalist?

Via The New York Times: The increasingly fine line between mainstream media and cyber news sites may become more blurry as Apple files a lawsuit to issue subpoenas against three Weblogs that hosted links to a future Apple device on their Web site. The Web sites are now required to disclose their confidential sources, much like journalists for print or broadcast media are asked to. David B. Sentelle, a federal judge hearing the appeal last month, said this being the Internet age did not provide "clear lines for defining who is entitled to journalistic protections." However, some seem to think that bloggers should enjoy the same privileges that mainstream journalists do. "Bloggers are becoming a more and more critical source of news," said Kurt Opsahl, the lawyer representing PowerPage.org and AppleInsider.com. "A lot of confidential tips first start out on the blogs before being picked up in the mainstream media."
