You said perfectly exactly what I was thinking. What a bunch of brats who don't get how the echo chamber works. Of course people who read Salon already know Palin is awful, but millions of Americans don't, including presumably some family and friends of Salon readers. More ammo is always good when trying to convince the low information voter, of which all of us know some.
Further, you're absolutely right that Salon is still a respected media outlet, though known to be partisan, but still credible enough to be linked-to by compilation blogs and more mainstream media outlets. People who like to watch Joan on MSNBC come here out of curiosity. Though not permanent members of the letters-pages illuminati, these people are still welcome here, and deserve to know about this kind of in-depth reporting.
Realize that there is a whole nation of people outside of this little island of liberal like-mindedness. Keep these articles coming.
