We have been using many of the principles and patterns of DDD over the past many years. During domain modeling we have often used the concepts of boundary contexts, entity objects, value objects, aggregates and repository pattern, etc.
But based on my humble experience, I think DDD is much more than the usage of these patterns. DDD is a "thought-process" - the way you think about the problem domain, the way you interact with the domain experts & business stakeholders and the way you articulate the technology realization of the business need. This in a nutshell is the greatest boon of following DDD. The business and IT speak the same 'ubiquitous' language and this in turn bridges the "Business-IT gap" :)
That's the reason, the famous DDD book by Eric Evas states that DDD tackles Complexity in the Heart of Software. Mapping your software model as close to the real-life domain as possible helps us in managing the complexity of our design solutions.
The Microsoft Spain team has some pretty good documentation on this philosophy of DDD, which is available for download here. Also a neat ASP.NET example of a n-tiered DDD application is available for download.
