I whole-heartedly agree with you on this. Large SharePoint installations may need human librarian to properly catalogue the data. SPS Workflow espouses the view that information should always run through a workflow before being excepted into the repository. At the end of the workflow, in the case of documents, images, etc, they should be sent to a librarian (or perhaps information architect) to be properly tagged (with tag selection provided at the beginning or at certain steps of the workflow).

The File Server vs SQL Server is a big challenge to ITs, for many reasons (back and restore and others)

Thanks!
