I found the review by Dave Crocker [1] interesting. Instead of reading the latest revision of the draft I wrote a draft [2]. I read what Pete Resnick said about consensus after that to compare notes.

The intended status of draft-resnick-on-consensus-05 is Informational. What we have here is a document about consensus which will reflect the consensus of the IETF. Should the document reflect the consensus of the IETF or not?

In Section 1:

  'Our ideal is full consensus, but we don't require it: Full consensus
   would allow a single intransigent person who simply keeps saying
   "No!" to stop the process cold.'

The above introduces the term "full consensus". I took a quick look and I found at least one occurrence of the term in IETF discussions [3]. However, none of the IETF process documents use that term.

  "If the chair of a working group determines that a technical issue
   brought forward by an objector has been truly considered by the
   working group, and the working group has made an informed decision
   that the objection has been answered or is not enough of a
   technical problem to prevent moving forward, the chair can declare
   that there is rough consensus to go forward, the objection
   notwithstanding."

The word "objector" emphasizes that there is one person who dissents. My preference is to consider the objection and address it instead of viewing the issue as dissent from one person.

   "This document attempts to explain some features of rough consensus,
    explain what is not rough consensus, and suggest ways that we might
    achieve rough consensus and judge it in the IETF."

The title of the document is "on consensus and humming in the IETF". According to the above sentence the document attempts to discuss about rough consensus. In my opinion there a nuance between "consensus" and "rough consensus". As a quick reaction I would say that rough consensus provides a faster path to shape up a proposal. It helps to cut down on document delivery time to the IESG. The consensus part is sought by getting a broader perspective.

Section 2 sounds like objection-based processing. A binary choice (re. technical question) can end up polarizing a discussion. The section provides a good discussion about lack of disagreement.

One of the questions I wondered about is whether the person making the determination should use technical judgement or whether the person should only make a determination about the comments received. I mentioned in an unrelated discussion that if it is the consensus of the group that the sky is green, that's what goes in the document. The person making the determination can flag it as an issue as a matter of technical judgement. I'll highlight a point from Section 3:

  "Remember, if the objector feels that the issue is so essential that it
   must be attended to, they always have the option to file an appeal."

There are very few people who exercise that option.

According to the title of Section 4 humming should be the start of a conversation, not the end. BCP 25 states that:

  "Consensus can be determined by a show of hands, humming, or any
   other means on which the WG agrees (by rough consensus, of course)."

I am not sure whether hums are for a starting point or not. It can be argued in different ways, for example, see Section 4. Humming helps to get a sense of the room without people making a decision under duress. It is a useful way to resolve a controversy. I would say that it ties in Section 5, i.e. consensus is the path, not the destination. A show of hands is a disguised way to vote [4].

Section 5 identifies a few issues with the way people talk about "consensus". I understand what Pete Resnick wrote as he has explained that to me in an unrelated discussion. The text discusses about "making the call". I don't know whether the reader will easily understand the meaning of that.

Section 6 and Section 7 attempt to explain that a high percentage of votes in a direction does not necessarily mean that there is rough consensus for that. I agree with the conclusion in Section 8.
