John Newton was one of the founders of Documentum and, as a result, one of the inventors of what we now call "content management." Whether you like that term, or not, the idea of specialized databases that keep track of things like documents, Web sites, photographs, and so on has had a huge impact on our world.
Now John is the CTO of Alfresco, an open source company building open source tools for managing content. John wasn't always an open source advocate, but now believe it's the right model for creating enterprise software.
Scott Lemon, Ben Galbraith, and I spoke with John last week for our Technometria podcast and I just posted our conversation with John on IT Conversations. Take a minute and listen. I'm sure you'll enjoy it.
