Good point!

Well, I did not intend to say IETF does everything right, but their signal-to-noise ratio is better by orders of magnitude.

Also, I'm under the impression that IETF learned from that utter failure and took measures to prevent similar mistakes in the future (please correct me if I'm wrong).

I did not observe that W3C actually learned anything from their mistakes, but produced less and less useful things over time (again, please correct me if I'm wrong).
