Unless you've got a unique selling proposition, that is. Murdoch doesn't.
A magazine like Cook's or the Economist can charge for access, because they offer writing that's leagues beyond the norm. The Wall Street Journal, on the other hand, is a good paper, by it offers nothing that I can't find elsewhere. It's certainly not a Top 5 news source for me. So people likely won't notice if the WSJ disappears from Google.
Murdoch is smart, one of the brightest men alive, but here for the first time in decades he's met a system smarter than he is. On a level playing field he's a shark, but he is no longer a holder of a primary source of power. I forget who wrote yesterday that the Internet isn't about content, it's about access nodes, but they were spot-on. Murdoch can crush wtb content, but he doesn't own nodes and he doesn't understand them.
