Yahoo (NSDQ: YHOO) has announced a small acquisition in the news space: it has bought news aggregator and blog tracking site BuzzTracker. The site’s founder Alan Warms has joined as GM and VP of Yahoo’s news division. Chicago-based BuzzTracker aggregates content from news sites and blogs, then organizes the content into various topics. The software is also being used as a white-label on other sites such as TVWeek.com. No price was disclosed, but should be in single-digit millions.Warms writes about it here on his blog.

So it looks like with adding the automatic aggregation capabilities of BuzzTracker, Yahoo news will expand from beyond a directory/human-driven news aggregation site. This will also move it into Google News and Digg territory, while Google is trying to move into the human-editorial side with the AP/AFP/PA deal announced last month.
