That's the point, I think: the judge shouldn't have decided the question of whether the shield law applied to bloggers, because it wouldn't have provided a shield in this case anyway.
edit: Though come to think of it, maybe the judge though that was the easier question (wrongly, imo), and so looked at it in the other direction: since we can decide that bloggers aren't journalists, we don't need to unnecessarily decide the question of what behavior the Oregon Shield Law shields.
"Oregon law provides special legal protections against defamation lawsuits to journalists associated with traditional media outlets. Such publications are immune from defamation suits unless the defamed individual first requests a retraction. Journalists at recognized media outlets are also protected from revealing confidential sources. Cox argued that she was eligible for protection under both provisions and asked the judge to set aside the verdict."
