@Gargron the problem with welcoming large corporations into open systems and standards is the old "embrace and extend" ethos. They will start to push for changes that don't "fit" with the Way Things Are Done, and people will say no, and they will say "ok" and implement it on their side. Then their users will start to complain that features used by meta users don't work properly elsewhere, and meta will say "well look, why don't you ask your server to implement ..."
