The blogosphere is screaming that Yahoo killed its blog search. Wrong, they just removed it from the News Search index. Kevin Burton points out that Yahoo still includes blog results in web searches just like Google and MSN Search. Jeremy Zawodny of Yahoo confirmed that Yahoo did indeed remove blog results from the NEWS index. This makes sense to me. News Search is for news. There are lots of specialized search indexes for things like job search, people search, product search, mobile search, video search, etc. Why put blog results in News Search?
The funny thing is that Yahoo still has some blog results in its News index. For example, Search Engine Roundtable, a blog, shows up in a Yahoo News Search query for "Yahoo Search". Results from Gawker blogs also show up in queries. So, maybe the more accurate statement is that Yahoo has removed most blog results from it's News Search index. Google does the same thing, including a result from blog.searchenginewatch.com, ...clearly a blog. MSN Search returned pure news results as far as I could tell.
