Towards Personal Workspaces talks about the evolution of personal workspaces in an enterprise. It covers challenges, technologies and some of the portal players.
Information is power: Organizations that exploit that power will successfully grow their businesses. The challenge for most companies, however, is managing exponential information growth while connecting users with the data, content, applications and processes they use in their various roles. The solution is to create role-based personal workspaces.
I wonder when Personal Portals (offerings from Microsoft, Google, Yahoo) become the front end for Personal Workspaces. I think they can both co-evolve easily to provide a more complete offering. After work vs personal knowledge is just a matter of context.
