I don't think this is all so spot on accurate...
If I want to take on a new hobby only 2 roads come to my mind:
1- I ask a friend that does the activity in the first place if he/she can teach me.
2- I pay a professional to do it.
Both of them are basically "go find someone to teach me".
I don't know why gaming should be different. Everybody always try to say how games are the new medium to entertain and/or tell a story, the new books the new movies, etc. ¿Do you expect to learn how to read only by buying a book?. But I´m not saying it is impossible because the analogy stops working being that nobody has to be taught how to see a movie (except those people that though the train was REALLY going through the screen).
Another thing, unless you are a really impulsive person you wont buy all the things before having a clue that you might get the hang of it, maybe renting a surf board and having some classes before buying the board and expecting it to teach you how to use it.
Also games do go a long way to teach you how to play, the fact that there is a tutorial and a difficulty curve proves it. And if you have two brain cells to rub together but don't know what R3 is, you try every button and if that doesn't work you go check a manual, and if that doesn't work you ask somebody, and if that doesn't work you go look online (and the people that uses farm-ville knows how to google, hell my mom knows how to google and she can't even access her facebook account).
The information is there and not everybody that knows it now was carried by the hand THE WHOLE WAY, at the most they got themselves to ask for help.
People that play farmville want to play farmville, they are not sitting there moaping wishing they knew what to do when that tutorial tells the to crawl under the pipe...
