This thread is meant as a place to discuss the utility (or lack of it) for longer tags.
Currently, tags can have a maximum of 25 ASCII characters. That leads to interesting results such as differential-graded-algeb, synthetic-differential-ge, and computational-number-theo. While these are certainly marginal cases, they appear occasionally and are quite legitimate.
There is also an intrinsic use for longer tags, since they allow for more descriptive and specialized tags: for example, 'infinite-dimensional-manifolds' or even 'locally-convex-topological-vector-spaces' (these are probably not the best examples; perhaps you can suggest better ones).
In view of the above, I would like to ask people to give their input on the possibility of increasing the maximum length of tags:
How useful, or not, would this feature be?
What are the advantages and possible use cases?
What are the disadvantages?
Is it technically feasible?
Other opinions and comments...
In case this discussion leads anywhere and there is support for increasing the maximum length of tags (say, to 30 or even 40 characters), then this could be turned into a feature request.
