My company has an anonymous internal forum and I don't even like asking simple HR questions on there! I once complained about my disuse of my dependent care FSA going unnoticed. That's as far as I'm willing to go.

A touchy subject like this from someone with a technical background to a large group of people... I guess Google has a lot of employees and it was bound to happen eventually but seriously, how do you hit send on something like this without some twinge of anxiety?
