As we talk about anonymous sources, I'm reminded of some chat we had where an anonymous Twitter egg purported to work at a morgue or some such thing while tweeting at a political provocateur. The tweet was taken with some measure of seriousness by a person or two, saying "well, if he actually had that job, he couldn't go public and keep it."
I try to be moderately skeptical and not flip my lid too much at such things. Hopefully I'm doing an OK job.
