Google News has started to separate blogs and news links, according to the Google Operating System...
"When you view a cluster in Google News, there's a new option to filter sources: you can restrict news articles to blogs and to local news sites that are relevant to your query. The filters are a good way to find opinionated articles and more up-to-date information from local sites."
I never understood why they have a separate search engine for blogs. Further, this just blurs the line. Take a look at this cluster of blog links on Obama, which includes a lot of traditional media blogs. All of this is becoming a giant cake mix as the Google Web index gets faster. It's not so easy anymore to keep the pigs and cows contained.
