In the post Moving from design to reality - building HedKandi.com in Microsoft Office SharePoint Server 2007 at the ECM Team Blog , our blogging colleague Ben Robb talks aboutwww.hedkandi.com; a web site developed by his team for Ministry of Sound. The good thing is that there's a full MOSS-based portal.
Is very good to see how the MOSS usage is increasing around the world and how both ECM capabilities and the out-of-box ASP.NET 2.0 integration turned easier a lot of tasks that used to demand so much effort to be done, such as interface re-use by dwt templates and portal-level content definition by custom lists and document libraries customization, which now are addressed by the Master Pages and the Content Columns/Types, respectively; not to say about another .net framework features like security providers, workflow, etc...
Thus, we have gained more project time to spend with portal's architecture and conceptually approachs to meet both business, content and collaborative requirements.
So, it makes me just enforce my opinion that MOSS is going to become a solid and powerful platform not only for enterprise level portals, but for the most varied sort of web scenarios, as well.
