I have posted a couple of time about social tagging/bookmarking in the enterprise and i believe that it is one of those Web 2.0 tools that will reap a lot of value in the enterprise space because of its natural fit into knowledge management needs.
The Intelligent Agent Blog written by Robert Berkman of Information today has a good review of free, public social bookmarking sites that could also be suitable for enterprise use. He reviews many of the services that have been out there for a while and also reviews some new ones that i was not aware of. In addition he posts that on April 15th he will share a full article, which also contains a detailed feature comparison chart of both fee-based and free social bookmarking vendors and sites. I am really looking forward to this article since i am working with a handful of customers that are starting to seriously evaluate social tagging as a solution for their enterprise.
Social tagging & bookmarking has great potential for not only helping enterprise users save, organize and share information with each other but for natural extensions like expertise location. I am confident that it will become a common solution for enterprises. Just this last week, Rich Hoeg from Honeywell announced the launch of Connect Beam's enterprise solution.
