Do we really need version history of documents?
This is something that's been bugging me for awhile so I thought I would throw it out there. "Is it really worth keeping version history of documents?". Other than legal reasons, I can't see why any would need version history of a document. Source code. Sure. Absolutely. A document? I'm beginning to think that there's no real reason why history is that important.
Look at a document. Okay, so you'll be able to go back in time and see that Joe added a paragraph or something. If you use Office, this feature is already built into the product. If it's a binary file of some kind (like a PDF) you really can't compare or track revisioning in the document (yes, Adobe had this feature but you need special tools to use it). The only case I can see is a text file where you can do diffs of the versions, but then why would I really care?
Retaining history seems to be so important to some, but I wonder if that's really the case? Maybe take a look at your documents and try to justify why you think you need a complete version history. Is it really worth keeping in the long run?
