As Yahoo! starts incorporating some 750,000 blogs into its news pages, some media critics are worried visitors won't be able to tell the difference between real news outlets and the blogs. Granted, blog search results will be physically distinguished on the page from MSM news items, but still: The potential that the two could be confused exists, so it's time to worry.

Yahoo, meanwhile, just wants to provide readers with a full, 360-degree experience. (Get it? Yahoo 360? No? Okay.)

In a prepared statement, Neil Budde, general manager of Yahoo! News, says the company wants to fuse professional journalism with so-called citizen journalism to provide a fuller spectrum of content to its members. Still, Yahoo! is clearly sensitive to the dangers of blurring the lines between professional and amateur journalism.

But it's simple to tell mainstream news from blogs, really: One publishes sensationalized stories, titillating headlines and racy photos — the other fact-checks.
