What's next for CSS? Probably CSS Current_Version+1, designed by committee, late, missing really desirable and important features and including really lame and awkward features, not exhaustively specified and not implemented completely by anything other than Opera, and not done in the same way on all browsers.

Is the future more rosy because it works as an imagined place without the thorns and caterpillars and fungi and drought and hay fever and pollen allergies and cheap imported roses and Monsanto seeds?
