The open source movement has been amazing in the enterprise. We have been working with Liferay for a while now, and find it to be getting better each day. The nice thing is, we can literally see it get better each day with direct access to the source over the web along with detailed commits and much more than ever anticipated we would ever know about our enterprise solutions. I believe that this is an example of transparency that makes the open source environment even more compelling.
Not only are these capabilities helping move along the open source environment and introduce pressure for further transparency by close-source vendors, they also begin to outline possible options and framework for enterprises or even smaller organizations undertaking internal development with mature development methodologies.
