The provided passages do not contain information about the practical implications of the ideas presented in "You Are Not a Gadget." The passages only offer a description of the book, mentioning Jaron Lanier's arguments about the Internet's failures and his perspectives on Web 2.0 [1]. They also touch on his optimistic view of the Internet as a cultural vehicle [1].
Therefore, I cannot answer the question about practical implications based solely on the given text. The passages do not detail what those implications might be.
