A new tag tensor-calculus was created.

Q: Curl as a divergence... Is it possible?

I want to know if it is possible to express the operation $$ \nabla \phi \times (\nabla \times \mathbf A) $$ as the divergence of second order tensor field $T$. Here $ \phi$ is a scalar field and $\mathbf A$ is a solenoidal vector field ($\nabla \cdot \mathbf A=0$) I have used all possible id...

And what about another newly created tag icm-2018? There is a post about similar tags icm-2014 and icm-2010 suggesting to replace them with either icm or conferences: meta.mathoverflow.net/questions/194/help-improve-tagging/… It has score 5 at the moment (no downvotes).

A: Help improve tagging!

We just got a question tagged icm-2014 and we have icm-2010 (with two closed questions tagged with it). I think it is not necessary to have separate tags here and one ICMs tag should suffice. Actually, I do not even think this ICM tag is necessary, conferences should suffice. The numbers o...

Two comments under that post:

I think this is a good suggestion. However, I wonder if a new answer in this thread with lots of other answers still attracts significant attention... — Ricardo Andrade Oct 17 '13 at 19:35

Likely not significant one @RicardoAndrade, but basically it suffices if François G. Dorais (or another moderator) notices. — user9072 Oct 17 '13 at 22:23

Usually on questions about tags there is not too much discussion. For example, Alex M. had two questions not too long ago, only one of them got an answer: Does it make sense to have both “surfaces” and “curves-and-surfaces” tags? and Tags “riemann-zeta-function” and “zeta-functions” are almost identical.

His recent question now got into the community bulletin, so perhaps this one will gain a bit more attention: Removal of the “symplectic” tag.

François G. Dorais' assessment that there is not that much interest in tag-related discussions seems to be correct:

In the early days of MO, there was a lot of tagging discussion which helped draw guidelines for what other tags might be useful and appropriate for the site. These days, however, only a handful of users are interested in tagging issues, probably since the system works well enough for everyone.

Q: Should there be a separate tag for videos?

Sometimes there are questions about videos, movies, documentaries, etc. (I'll add a small sample below.) Would it be useful to have a separate tag for this topic? This could possibly help when searching for such questions. Or would such tag be too specific to be actually useful? Some of those ...
