We have talked a little about some of the business aspects of how Web 2.0 might be leveraged within a business organization, but the reality is that in most cases, a business case must be used to determine and drive all aspects of IT. It does not make sense for the development team to start building new interfaces unless there is some business driver and a known return on investment. Defining the business goals and requirements should be a first step with any approach. Some amount of learning and testing new technologies should be encouraged within any IT organization; however, business drivers outweigh resumé building by the development team.
In contrast, one of the goals that should be set is to fully acknowledge the feedback gathered from our users as they interact with the tools we provide. Without a complete feedback loop, much of the effort might be wasted. One significant benefit of Web 2.0 and Social Networking is that it is now so easy to find content that is interesting, relevant, or just popular. Tagging and rating allow "good" content to rise to the top of any list, and comments allow us to understand whether other users have found things useful. This aspect is changing the way we work with the Web and others.
