In most Slack channels, one of the permitted topics of conversation is
the topic of the scope of the channel itself: it is acceptable to
discuss what topics are appropriate for discussion in the channel.
However, there are some abnormal channels in which discussions of channel
scope are inappropriate, and should take place elsewhere.
For example, consider a trivial channel
#void where any discussion
is deemed off-topic. I created one of these last week, in a sort of
Slack-channel-creation-shitposting move. Or less ridiculously,
consider a channel with an automatic feed of some sort of news; maybe
indicent reports or support tickets or something of that type.
Discussion of the news itself, as well as meta-discussion about the
channel, might reasonably be deemed off-topic.
Discussion of what is on-topic for abnormal channels should take place
somewhere, so one naturally wants to create a
#abnormal channel to
host discussions of what is on-topic for that various abnormal
Now suppose you need to discuss whether something is on-topic for
#abnormal? Where do you do it? Well, there is no real problem; you
can discuss it in
#random, which, despite being dual to
somehow not ridiculous at all.
But you definitely can't do it in
is only for discussing the topics of abnormal channels, and
#abnormal is itself a normal channel. Or if you disagree and say
#abnormal is abnormal, then you have just said that
#abnormal is off-topic in that channel.
(Note that there's also no real problem with
#abnormal itself. It
can be either the channel for discussing all abnormal channels, or
the channel for only discussing abnormal channels, take your pick.
It just can't be both at once.)
Emanuel Buholzer suggests that such discussions could take place in
private messages, outside of any channel. This shows that he
prefers Morse-Kelley set theory to Zermelo-Frankel.
