comment How should basic questions about transfinite ordinals and cardinals be tagged?
@HenningMakholm I wasn't calling that into question, just pointing out that some of the topics within algebra-precalculus don't seem especially related to one another -- although certainly none of them could be called abstract algebra.

Well, perhaps platonic-set-theory vs formal-set-theory makes it clearer.

@AsafKaragila Johnstone!

E.g., algebra-precalculus seems to be based on which subjects tend to be taught together, so I can understand ordinals coming under set-theory on the same grounds.

@HenningMakholm It would depend on the question itself, but I don't see why a 'pure ordinal theory' question would need to be explicitly tagged with set-theory. It's not a problem if it is, since there are far more arbitrary groupings of topics into tags on this site.

comment Curve resemblance to Closest Shape - Question on Hold - Advice for clarification needed
Better: ask a question "how can I define closeness of geometric shapes?", get an answer, try and implement it yourself, and then if you get stuck ask a second question: "using this definition, how do I find the closest shape?"

comment Are others irritated like I am with the use of the word “domain” in questions?
What would we say the domain of the function $\frac{\sin(x)}{x}$ is?

comment Should the overuse of colored text be discouraged?
I like how one of the colours is called 'greed'.

comment User disagreements in comments
I think that the first sentence of this post would be a more appropriate title than 'User disagreement in comments'.
