A year ago, Jeff added a paragraph about how downvotes on meta are different to the FAQ.
That's a step in the right direction, but people still frequently get pissed off by Meta downvotes (because of course, no one ever reads the FAQ). Newbies will feel personally attacked; some will withdraw and hate Meta from then on, others will complain, but either way this frequent misunderstanding adds an amount of completely unnecessary drama to whatever discussion people are having.
I realize there is a culture of being "initiated" into Meta and you either get the culture here or you don't, and that's okay to a point, but Meta is supposed to be the capital of a huge Q&A network, and needs to be more open to those who don't get it.
MSO should show the FAQ message explicitly, on a separate page to first-time posters when or before they post their first contribution, similar to the "did you do your homework?" page on SO proper.
