So are we journalists?

Buffy, the San Mateo, California police department obtained a search warrant, broke down the door of a Gizmodo blogger and seized his computers, phones, bank records, hard drives, etc., yesterday. He had blogged about the "lost" Apple iPhone (complete with video pictures) before Gizmodo returned the phone to Apple. Gizmodo sent letter to police department demanding the return of all confiscated items saying blogger, who works from his home, is a journalist for Gizmodo (even if perhaps Gizmodo or the blogger had purchased what might have been stolen property) and therefore information about his sources of information were protected from search and seizure by the First Amendment.

Are all are bloggers journalists? Are we now journalists with special First Amendment protection (protection of our sources)? Will this question rise to the Supreme Court? Isn't it great to be a blogger?
