EDIT: I also seem to have trouble getting titles right on submission to HN. In this case, the reason it's even news that this was released is because it had been a secret document in the past. I feel like the edited title removes a crucial piece of information about this story. Even if the content itself is not particularly revelatory, it speaks to a bigger picture (perhaps even more effectively due to its mundane nature) about the almost comical lack of transparency in certain aspects of the governing process.
EDIT2: In trying to think of other words to replace secret, I kind of hit nothing much because most of those words (such as: mysterious, covert, classified, etc.) evoke the same linkbait-y feeling. Not sure if there is really a good replacement choice.
What does it matter who's following these rules? Do you really care whether a senator has properly installed a [Chair (Overstuffed)] in their personal office rather than their front office?
I'd be more worried about the opposite phenomenon. The handbook is apparently used by the Senate Ethics Committee. I'd be worried that a giant book of rules about how exactly to obtain your parking pass or requisition an easel or how to arrange chairs in the rules committee room (note: actual examples) could easily be used as a weapon against individual senators by accusing them of "ethics violations".
Rule violations by senators are a tricky thing. Senators do not in fact serve at the pleasure of the Senate Ethics Committee. They're elected by the people of their state. The Constitution requires the Senate to make its own rules, but those rules are primarily for the orderly conduct of business in the Senate.
