Well, without knowing how people would have voted in an ordering
system, it's hard to compare.

Can anyone think of other issues which haven't reached some
compromise after the come to the mailing list?

I'd like to see something similar happen in this vote if possible,
hence the later suggestion of some way for options to join and leave
the vote.

-ve = negative = all voting options below 0.

In the positive-negative range voting, some average is the
result.  I don't think we need to use truncated mean (the mean
vote ignoring the highest and lowest N% of votes) and I think
I prefer the mean to the median, but it's a choice we can make.

A far more learned expert has criticised that article much more
robustly than I can, but I feel that a basic principle of
consensus-building is that a majority should not overrule a
substantial minority.

I'm not sure how we'd do that?

That is exactly the debian ambiguity problem to which I referred!
I really don't want us to vote 98-to-2 for GPL-2 for example, then the
2% interpret it as a wish to start the process all over again.
If we want further discussion, we should vote for further discussion
explicitly and not have a possible stand-in.

I know voting for GPL-3 would be going through a one-way door, so we
couldn't vote to return to GPL-2 later (well, probably not and at
least not without a lot of work) but if we want to retain GPL-2, we
should vote to retain GPL-2 and then the project should remain GPL-2
for a while.

So is everyone OK with a "further discussion" option being present?

I think it could, but I don't know of experiments about it.

This may be a difficult question to answer.  The common process
I've seen elsewhere is if an option gets some required number of
supporters, then it is added to the ballot.  If enough supporters
revoke their support that it falls below the requirement, then it
is removed.

I think the most obvious possible new options are additional
permissions or exceptions on top of each licence?
