Here[1]. Saying "wasted" as a status update can affect a credit score. And even if it isn't disclosed, employers, and other entities, may use your Facebook activity. This is a totally valid issue. So, yes, Facebook does matter, whether you like it to or not. It isn't just a toy, and you can't just stop using it, without it potentially harming you. I think it's totally unfair, but people now have to consider their online presence when hunting for a job.
And they don't have to ask for your Facebook account specifically. Companies like ru4.com can tie your financial identity to your social media identity[2]. Just like how even though you didn't submit anything to the 3 credit bureau, they will find data for you, it is also becoming true with social media. I can't log into chase.com without allowing scripts from ru4.com. Luckily, I use a sandboxed Firefox profile, that has never touched Facebook.
