Thematic blog tracking service

blogrunner.com : thematic blog tracking service

blogrunner.com is a free service that tracks articles from online publications such as newspapers and blogs.

These articles are assigned and republished to various blog-aggregators that are the blogrunner.com network. These blog-aggregators thus archive the tracked articles coming from a defined index of sources.

The The Annotated New York Times, which tracks blog postings that cite articles published by The New York Times.

Among the things you can do with this site: track what the blogosphere is saying about a specific article; track commentary related to all New York Times coverage of specific topics; and track commentary that discusses articles by specific New York Times.

"These blog fragments are grouped by author or by topic to form virtual, distributed conversations that span multiple sites and that center around the coverage of news events as reported by the Times," as the site describes it.
