I think we should be able to have a minimum of two levels of details, with the brand also added only if needed for clarity. An exception, for use of additional sub-tag, should only made for unusual sub-classes of existing complex tags.
Argument 1: Search
If a question is raised, it should be possible to find other similar questions (and answers). As there is no control of style or approach to question wording, this is best achieved by informed individuals setting (or correcting) the tags associated.
Minor Rant: It is not overly useful when someone removes tags (or complete definitions) when they either don't understand the issue
being discussed or the effort required to find (and re-tag) questions
in the first place.
Argument 2: Change
We need to clearly differentiate (sometimes rapid) changing use of technology: use of ARM (vs x86), netbook (limited screen height), and smartphone (small 4" screen), tablet (7", 10" screen), Unity (vs Gnome), touch (vs. mouse), multi-touch, etc.
All of these factors are critical IMHO factors to the aim of Ubuntu being able to smoothly adapt to running on everything from smartphone, desktop, server, thin-client, tablet, to cloud.
