I like that, especially given the perennial habit of some employers to mine Facebook for reasons to mistreat employees, and also to ask for prospective employees' Facebook account credentials. And there seems no reason to expect the same weirdness that comes from likening a web application to an abusive partner.

"I mean, imagine you're interviewing for a job, and the hiring manager asks you for the password to your Facebook or your email. Yeah, maybe you can say 'sorry I don't give that out' and still get the job - but at that point, do you want to? And what the hell is even going on that that's a question you get asked?"

Yeah, I think maybe you've given me my new metaphor. Certainly I look forward to trying it out. Thank you very kindly!
