From our extensive correspondence with literally none of you we know that you all have pressing life questions such as "How many of my CSS heroes will I meet at CSS Day?" and "How many flamethrowers will they aim at me from stage?"
The answers are lots and probably none, respectively.
You trust us, right? I mean, we're very protective of our target audience.
