Rupert Murdoch's MySpace blunder
Via Romenesko :
MySpace has become a textbook case of how quickly a digital juggernaut can become a has-been, writes Matthew Flamm. The head of a research firm tells him: "It may be that Rupert [Murdoch] is ultimately a newspaper guy. The idea [with MySpace] may have been, 'We bought you, so make it happen for us.'"
Perhaps Rupert just couldn't figure out how to force one point of view  down the throats of a few million users.
Go! Do things internets! I command thee!
