CARLSBAD, Calif -- Bing, the new Microsoft search engine debuted here yesterday, is different.What impressed me most is how Bing creates rich, well organized environments to research, find entertainment and to buy things. If owned an e-commerce site, or entertainment destination site, I would find this very threatening. I think it's a big deal. So why is Bling different and will it succeed? Hanging out in the press room at D: All Things Digital earlier this week, I has the good fortune to get the perspective of two of industry's most insightful writers, Erick Schonefeld, Co-Editor of Techcrunch and Ina Fried, lead Microsoft beat reporter at CNET News.com.I spoke with Ina on Tuesday before the launch and Erick yesterday, immediately after the Ballmer presentation.For more perspective on the Bing and how it creates unique informational environments, check out Esther Dyson's post on the Huffington Post.
