Jason Goldberg's take on which blogg-ish news sites are scalable and which will struggle. Surprise answer: Drudge (because it is so lean) and Huffington (because of the network of external contributors).

Best example yet of a site integrating with social network? Four strong ideas: 1 Make relevant CNBC content available within LI, 2. Make relevant Ln content available within CNBC. 3. Make it easy for me to share CNBC content with my LI network. 4. Make it easy for CNBC to create content from LI network.
