By plagiarizing the work of actual journalists, apparently.
Afterthought: don’t get me wrong, I love the blogs. But I’m really sick of the current meme that blogging is somehow on a par with journalism. As I’ve said before, the relationship of blogging to journalism is mostly the relationship of the wood tick to the deer.
Lord knows I believe in the need for media criticism, and there’s no shortage of that in the blogs. And as compendiums of news sources in an era of information overload, they’re invaluable. But with a few rare exceptions, it’s just not journalism, and it’s silly and self-aggrandizing to pretend otherwise.
