Truthiness vs. truthfulness

This comment by Julia Hobsbawm in The Guardian sort of reminded me of a bunch of press wires I recently came across via PubSub and the whole deal with communication and authority. What exactly is a press release? I don't mean to sound like a complete idiot but I find the concept incredibly bizarre. The press needs to be spoon-fed? Try setting up a matching search in PubSub Press Releases to get an idea of what gets fed through these things.

What does this have to do with blogging and RSS other than the PubSub connection?

Judging by the rise of the commentariat, which blends fact and truth with opinion, and by the rise of blogs which challenge to some extent the notions of trusted truthfulness by "authority" media brands, truth still sells, but not as much as it could or should.

I'm not exactly sure why blogs challenge the notion of trusted truthfulness (credibility is hard to achieve in the blogosphere, and for good reason); and despite the mostly negative comments this comment got (or meta-comments, if you will), I found the piece kind of interesting. But don't take my word for it. [Source: Canuckflack]
