I think this is a great opportunity for programmers to be able to find a lot more answers through organic search. Previously you'd have to know that the topic was covered in _ textbook, then you'd have to buy and read said textbook. Now you can find it just from a Google search. And then you can read the whole textbook if you want. Seems worth it for $5.
