This may be the first real argument I've seen for the difference between blogging and journalism.
Blogging is one person's opinion or account of a topic.
Journalism is one person's opinion or account of a topic, as filtered, reviewed, revised, challenged, fact-checked, and approved by an organization.
It's reasonable to expect an individual to be able to decide whether they trust a handful of news organizations. If the NYT repeatedly breaks my trust, I can remove them from my reading list. But until then, I trust that the NYT to vet their writers. So I trust the authors published on nytimes.com without knowing a thing about them, because I trust the NYT. (Likewise, if I mistrust the org, I'll mistrust the contributors. Hello there, Fox News.)
It's not reasonable to expect individuals to be able to decide how much they trust each individual writer. I don't even know how many writers I read on a daily basis.
When it's a blogger, I take it with a grain of salt unless it's someone I read so often that I've come to trust them. (Hello, Jason Kottke.)
This doesn't make blogging inferior to journalism. I probably get more value from blogs than news sites on the regular. But I do think it's a valid distinction to take into account.
