Blog Pulse

BlogPulse is a useful free tool from Nielsen BuzzMetrics that lets you track trends in the use of terms across the blogosphere. You can compare up to three searches, and you can graph trends over 2, 3, or 6 month period. A tip: the search phrase can be a url, which allows you to compare blog citations. Here's a comparison of Google, Yahoo, and Microsoft mentions across the blogosphere for the last six months:

The active graph also lets you click on the trendline to pull back the actual search results. These graphs track mentions. They don't weight mentions by the blog's importance or readership. Thus, splog terms appear artificially high: Blogpulse shows more mentions of "get rich" than "george bush", which I suspect is due to spam.
