I don't trust any single source for news. Why would anyone think that they were getting unfiltered news from a website like Facebook?
I know folks are going to have to report to a Congressional Committee over this, but why is this a story? NBC leans heavily liberal, Fox leans heavily conservative, CNN does something which only people in airports actually see.
Facebook may get sued by those who pay for advertisements on their website, which may be fair, based on the wording of contracts.
Is it just because Gawker is screaming about this at the moment, that this is news? There is no unbiased news anymore, why does this shock or confuse anyone?
