Usefulness of Document Management?

Ace905 asks: "Document and Information Management are huge money-making courses for Colleges and Universities. A lot of web sites are dedicated to the concept of 'Records Management' - but they seem to receive relatively little traffic. Wordtracker's results for the term 'records Management' seem to show people search mostly for public records - looking to find information on themselves and celebrities. Two of the only Usenet newsgroups to discuss records management (comp.doc.management and misc.business.records-mgmt) are either incredibly under-read or filled almost entirely by spammers. How can this industry have so many resources dedicated to it, and yet be virtually ignored by almost every professional out there? What are your experiences in the field of records and information management? What are your views on this industry?"
