There's a measured take on the New Labour/Murdoch divorce from the Liverpool Culture Blog (http://www.liverpoolcultureblog.co.uk/2009/09/labour-on-the-sun-wrong-on-hillsborough-wrong-on-labour/ ), expressing unease at the invoking of Hillsborough as part of their spat.
Meanwhile, one blogger looks at a likely Cameron victory next year & notes that the Tories will take aim not just at the BBC, but Ofcom, too, hence Murdoch's switch; such a scenario could lead to a British version of Fox News over the airwaves (http://robinbrown.wordpress.com/2009/09/30/the-sun-drops-labour-but-there-are-wider-issues-at-stake/ ).
If it does come to pass, I say: Bring. It. On. Murdoch may think a UK version of his attack-dog channel will deliver the goods, but the reaction from the blogosphere will be just as swift, astringent & relentless as that seen in the US by sites like Huffington Post (http://www.huffingtonpost.com/ ), Raw Story (http://www.rawstory.com/ ), Media Lens (http://www.medialens.org/ ) & Media Matters (http://mediamatters.org/ ).
