re: Enterprise 2.0's New Debate: Dam the Streams?
Let's continue the metaphor(s) a little bit: Suppose the social stream is like a river, and the enterprise is like a city. Now, the city may choose to get water from the river, but it can't take the whole thing as-is, where-is. Pipelines, reservoirs and pumping stations, filtration and purification systems must be in place to get the water into the businesses and households in a form that's useful. It needs to have some pressure to get where it's going, and be potable or usable.
In the same way, Enterprise 2.0 must consider what intellectual (and perhaps technical) infrastructure it needs to have in place to take the river of information and turn it into "potable" form, filtered by people or technology - whatever means the enterprise deems appropriate. Social "fires" may need to be extinguished, and social "recipes" may need to be cooked and delivered. People with the skills and guidelines to do this work will need to be in place to make it all work.
