There are many interesting zeta functions, and the Riemann zeta function is the most notable of them. It is natural to expect that people who ask questions about other zeta functions would want a separate tag, and indeed, only a very small proportion of the questions tagged zeta-functions are about the Riemann zeta function. I think it would be better to ...

This question has generated a lot of discussion while I was looking away! Here are my thoughts. The primary purpose of tags is to aid with search. As mathematicians, we have a tendency to think in terms of classification and taxonomy instead, but this is not the best way to think of tags and we should make an effort to stay away from this kind of thinking. ...

It seems that these three tags are being discussed in this thread: infinite-combinatorics, small-uncountable-cardinals, cardinal-characteristics.The tag infinite-combinatorics exists for a long time, but it might be good to improve the tag-info. Whether or not the other two tags should be created is part of this discussion - again, clarifying the content of ...

Unlike what another answer suggests, I think that "continuum hypothesis" is not a good tag to use as a proxy here. Instead, I assume many of these questions would be about "cardinal characteristics", so maybe we need such a tag. It seems to me that "cardinal characteristics" would be more useful than the proposed "small uncountable cardinals", which seems ...

Given the discussion, I tend to be gradually convinced that creating small-uncountable-cardinals is a good idea, and a good counterpart to the existing quite broad large-cardinals, which currently has almost 500 occurrences. I initially expressed that all this could be embedded into continuum-hypothesis, but several people have argued against this and I'm ...
