They started adding it to questions across the site: 13 in total.
Being a low rep user, these retag edits had to be approved by several other members of the community, and they were: 8 independent reviewers (including one of our moderators) approved these retaggings — and there weren't any edit rejections. That moderator even approved the creation of the tag wiki.
Now, another one of our moderators has stepped in and removed this new tag from all of the posts it was added to.
While I would have preferred a discussion about this (potential) tag beforehand, personally I did think it was a good tag — and apparently so did the users who approved the edits.
Why has the tritone tag been removed without a discussion?
I don't really want this post to be a discussion about the merits (for or against) the existence of the the particular tag — though that would make a good topic for a separate post.
I want a discussion about what's happened here, and why. Because it seems to me like the community/process has struck a discord.
