Breaking the press monopoly is one thing. But the internet has also broken the political monopoly. Ten or even five years ago, when the Minister for Widgets put out a press release, the mere fact of his position guaranteed a measure of coverage. Nowadays, a politician must compel attention by virtue of what he is saying, not his position.
It's all a bit unsettling for professional journalists and politicians. But it's good news for libertarians of every stripe. Lefties have always relied on control, as much of information as of physical resources. Such control is no longer technically feasible.
