I just stumbled into tags which start with "wood" (by searching for
[wood-*]). It's obviously that all the questions on this site have and will have to do with wood.
Do our tags need contain "wood"?
I think unless 'wood' is integral to a single word ex. plywood, the word wood is unnecessary.
"Wood" is probably too general a term for tagging in most instances, but it occurs to me that some kind of tag is needed for questions specifically involving the wood itself. Questions like "Which wood should I choose for my project?" or "What's the difference between black walnut and claro walnut?" An alternative tag, if it doesn't already exist, might be something broader like "materials", which would cover questions like the ones I cited, plus MDF, plywood and other stuff woodworkers use that isn't wood...
