I've read a bunch of takes on this new book by Jonathan Taplin about the monopoly power of Amazon, Facebook, and Google, but i really like DDay's, i guess because in addition to summarizing the points of Taplin's book he also takes issue with some of them (i.e. when Taplin sides with copyright holders in the battle against SOPA).

Personally i think all of this is a result of the fact that we're living in a game of Civilization where the player for some bizarre reason has decided to skip "Socialism" on the tech tree. By the time you have "Internet" you should definitely have "Socialism". Because a lot of these questions come down to "How do you make money on the internet?" (or, more and more, when the internet exists) and the answer really is "You shouldn't have to".
