What about moving away from the 'big names' to looking at small players and new entries to the search and content sector? I see lots of evidence that the new wave is small specialist search and content providers. The Wharton School's Knowledge@Wharton is a great example of becoming a specialist 'niche' information provider (business) and have teamed up with knuru.com to provide natural language search. Interestingly on the knowledge@wharton's knuru search you can order results by date or relevancy (no skewing by ads) and by strategic or news content. It also allows you to create contextualized summaries which are a great time saver.
But beyond Wharton and knuru.com I see lots of other good examples of an emergence of new approaches to information, content and search.
Thanks for the feedback, I try to highlight established and emerging companies, but I am always open to more. You may want to add your own headlines to Content Nation. Feel free to contact me for a login.
