Millions of websites will aggregate what we do, syndicate it, link it, comment on it, sneer at it, mash it, trash it, monetise it, praise it and attempt to discredit it – in some cases all at once. But no-one will actually go to the risk and the expense of setting up a global network of people whose only aim in their professional lives is to find things out, establish if they’re true, and write about them quickly, accurately and comprehensibly. The blogosphere, which is frequently parasitical on the mainstream media it so remorselessly critiques, can’t ever hope to replicate that.
