Quite a good idea in theory, but most people just want to get out and play straight away. There are the Video Tutorials which suffice as schooling for the newcomers (but many don't watch them, as like I said, all they want to do is play). Perhaps watching them all before being allowed to play (especially in multiplayer modes) should be a compulsory.
I personally think a practise chipping green and bunkers would be the greatest benefit to all players - this has been broached many times in the past but still has not eventuated.
