Dot Net Nuke as a core platform

One of the systems we use a lot is Dot Net Nuke - it's a Content Management System based on Microsoft.Net technologies. For us it's a near perfect fit with our skills set which include a significant team of .net developers.

We've found that the framework it supplies lets us concentrate on the clients requirements rather than on the more tedious areas of web development. We've extended the system a great deal and added event management systems, social web components, shopping carts.

Thats not to say we dont use PHP and other technologies but the benefit we see is the ability to build scalable and robust .net systems at speed.
