Link to Coding Horror: What's In a Version Number, Anyway?

I would agree with the contention that meaning full version names for the end user are best left to the year published. Point 2007.  But what then would you do if you have two releases Point 2007 sp1? could you sell a service pack?  Or perhaps Point 2007 R2.  I don't know what R2 stands for( Release 2).  At the very best this is not a question "developers" need be concerned with.  Strictly speaking Marketing will decide what "version" the user should see on the splash screen.  When it comes to the internal versions what Dev, QA and Support refer I like (Major).(Minor).(Full year).(days since January 1st).  Don't ask about two builds in a day :)
