I was interested to see Newsweek integrate blog commentary in a partnership with Technorati.

Dave Sifry describes the relationship in a post:

I'm proud to announce that Technorati and Newsweek are working together, including a deep integration of posts and links from bloggers (here's an example) into Newsweek's site. This includes the Newsweek Blog Roundup and summary widget on every Newsweek page (shown here on the right). This acts just like a "most viewed articles" or "most emailed articles" widget - only the determinations are made by watching the number of bloggers that are linking to Newsweek articles. It shows the top 10 Newsweek stories generating the most discussion on Weblogs within the past 7 days. You can see it on the Newsweek homepage and on each of the article pages, simply scroll down a bit and look on the right hand side. [Sifry's Alerts]

There are some other features also, including links to discussions about columnists.

This is a pretty interesting intermixing of mainstream and emergent, and will be worth watching to see how they co-evolve.
