The Economist has posted its research about how large enterprise companies (average size is 2.5 Billion dollars) are using Web 2.0 and how far do they see it taking them.
Overall it is a good description of what the business thinks of Web 2.0 and what challenges and expectations does it see for it.

The concept taken as Web 2.0 is defined by the reference to O'Reilly's Blog to be

• Blog
• Enterprise 2.0
• Mash-up
• Network Effect
• RSS
• Tagging
  
• Web 2.0 Concept
• Wiki
  

Which of the above concepts are used or planned to be used?


Companies are reporting that they focused their Web 2.0 efforts on blogs, wikis, and blogs primarily for internal improvements. Going forward, they see Web 2.0 impacting interaction with customers (68% of the surveyed).



79% of the companies expect increased collaboration to increase corporate revenue and 30% expect it to reduce cost by allowing less people to do more due to an easy access to information. Blogs are viewed as brand building tools and taken very seriously by many.



Other areas include improved customer satisfaction by allowing more customized services, which is clearly a view that Web 2.0 enabled applications are superior then older ones.

71% of the companies are planning on taking advantage of online communities which includes marketing on sites like MySpace, Facebook and the rest. However only 39% see the positive aspects of tagging as anything useful.
