Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
Last week a new Working Draft of the CSS Writing Modes Module Level 3 was published. This module covers BIDI and vertical text. Major changes since the last draft include an editorial overhaul, more details on the interaction of orthogonal flows, changes in requirements for horizontal-in-vertical feature, and some other minor tweaks to how things interact; no syntax was added or changed.
