Bart has resurrected his blog and is focusing on using portal technology in real-life applications. Allthough not as technical as Mart's Sharepoint blog, but certainly worth the reading, if you're implementing portal technology for your (internal) customers.

His first post, "Clients demand sharepoint, but sometimes lack portalvision..." , discusses the dissapointment some customers will feel, when they realise Sharepoint will not solve all their problems and world hunger, without a clear understanding what their problems are or without support from the entire organisation.
