Great post, Thomas! I can’t count how many times I have heard similar statements from my clients.

I also agree with Susan Scrupski’s comment that we can’t count MS/SP out, mainly because of their massive installed base and marketing machine. I don’t know, though, how they can properly address SP’s shortcomings without fundamentally changing their document/hierarchy mindset. IMHO, the concepts of documents/folders vs tag/search are the competing models for enterprise 2.0. For MS to really fix SP and not just do their usual marketing fix, won’t they need to move to a tag/search model where information is free flowing based on need? What happens to MS Office, when that happens?
