Yahoo! Search Blog writes: “Today we’ve begun the integration of blogs in Yahoo! News Search.
Now when you search on Yahoo! News you will see blog results as well as
content from thousands of trusted news sites. The experiences and
opinions published on blogs make a great addition to the mainstream
news people read everyday.”

Try it out by searching Yahoo! News for “yahoo blog search“.
Looks good although I’m a bit disappointed that blog results weren’t
integrated into the main index but were left in a sidebar. The
definition of a news website and a blog can get very blurred these days
- I’ve seen Slashdot described as both a news site and a blog. Same
with Neowin and Newsforge.

The index contains content from a
subset of blogs at the moment, but it will ultimately contain all blogs
which ping blo.gs. It’s nice Yahoo! are containing community content
and journalism. It would be interesting to see whether services such as
Google News, MSN Newsbot and Yahoo! News Search contain any blogs in
their main news index at the moment or Wikinews.
