This is one of my pet peeves, based on the early round of "bloggers are scary" fearmongering. You see, some of us might have undisclosed financial backing!!! Even then I was smart enough to know this was hilarious, because all of those people writing opinion pieces for our major newspapers were hardly disclosing all of their financial ties to readers.
I mean, sure, disclosure is good, but it was an example of trying to apply "rules" to bloggers based on journalism "rules" which didn't even exist at our elite newspapers. And still don't.
