Lessons learned, eh ?
"All we can do now is learn from the process "
And what have we learned ? That you do not allow Google to be in charge of the Web and its standards.
Any body that purports to create and maintain something destined to be a standard should have a multi-stakeholder Board and should take input not from companies but from experts and public opinion.
In a transparent and public manner. While publishing the minutes of the meetings. And ensuring that what is said is being done is actually being done.
In other words, do the opposite of ICANN and you can't go wrong.
