I have added cardinal-characteristics tag to some questions. (If a new tag should help when searching, it is good to add it it at least to more important post. But somehow this has to be balanced to avoid too much bumping of old posts - especially on site such as MO.)
There are some other possible questions which seem as possible candidates for this tag - but I do not plan to bump any of them just to add the tag (at least not in the near future.)
Some examples: Do sets with positive Lebesgue measure have same cardinality as R?, Hausdorff gaps and $\mathfrak{p}=\mathfrak{t}$, The dominating number $\mathfrak{d}$ and convergent sequences, How many closed measure zero sets are needed to cover the real line?, ...
... Is the Martin's axiom number $\mathfrak m$ regular, Intuition for the infinite cardinals p and t (now that p = t)?, Generalizing The Cardinal Characteristics of the Continuum and How many closed measure zero sets are needed to cover the real line?
