"The right role for a standards body is to wait till the implementors have deployed things and worked out the hard bits, then write down the consensus on what works and what doesn’t." [Tim Bray]
The rest of what a standards body does is commercial/political agendas, egos and "research tunnelling".
All very useful and important things in their own right but baaaaaad when then become W3C this or ISO that or ECMA the other.
