Yahoo News on Monday added results from blogs to supplement articles from professional news media, reports the Associated Press. A keyword search for online news will now return a list of relevant blog search results, displayed in a box to the right of the results for mainstream news outlets. Users can choose to view only the blog search results - including images posted on Yahoo's Flickr photo-sharing site - by clicking on that box. Yahoo's approach is different from the one adopted by rival Google.

Google launched its blog search offering last month; its separate, specialty engine searches only through blogs, while Google News hones in on mainstream news media.

"The traditional media doesn't have the time or resources to cover all the stories going on," said Joff Redfern, a Yahoo product director. However, he cited professional newsrooms' checks and balances to guard against incorrect or unsubstantiated information as one of the reasons for segregating the blog search results.
