Arpan Shah Microsoft Project and SharePoint Blog
The SharePoint team blog can be found at http://blogs.msdn.com/sharepoint/. This is a MUST read blog for SharePoint/CMS customers. Expect different Program Managers to start posting on the team blog. The first two posts are by Kurt DelBene and Jeff Teper - Vice President and General Manager respectively of SharePoint Products and Technologies. They lead the engineering effort for the technology.... and WSS "v3" and Office "12" SharePoint Servers is going to change the world. I don't mean that in some cheesy, idealistic way, I sincerely believe that it will change the way web applications will be built.
Subscribe to the blog, make comments as you wish... and if you're a SharePoint or CMS customer still unclear about the future of WSS, SPS or CMS, contact your Microsoft account team and get someone to brief you. :-)
