If you want to see evidence of why blogs continue to grow as a source for news, while mainstream media (MSM) sites appear stagnant, you need look no further than the latest announcement by the New York Times.
The NYT has announced the integration of Blogrunner–a news aggregator similar to Techmeme–a service it acquired in 2005. Take a look at the Technology section and you’ll see the "Technology Headlines From Around the Web".
That the NYT is adding news from other resources–including blogs–is not a big surprise. The newspaper is one of the few mainstream media sites that appear to "get" social media and are aggressively pursuing models that embrace citizen journalism.
