tools has many subsidiary tags: software, medium, writing-instruments, typing, handwriting. I have also seen resources used in conjunction with tools when looking for "how to" guides (example: Where can I find resources about writing “Choose your own adventure”-style books?)
I have neither found, nor been able to come up with, a question that would come under tools, but not under any of its subsidiaries.
Now, the fact that a tag has many subsidiaries doesn't mean we don't need that tag. And the fact that a tag is in effect a sub-tag to a broader tag isn't in itself bad either. (For example, it makes a lot of sense that more than one writer would have specific questions about Scrivener).
So far, the facts. Now, what I think.
- I would keep tools. Two reasons: first, someone might be looking for a software or hardware solution to a problem. Second, web tools: while they are software, people do not automatically think of them as such.
- Monica mentioned the possibility of adding hardware. Turns out we already have medium, but I think "hardware" would be a very useful synonym.
- Do we need handwriting and writing-instruments? Seems to me they could be merged.
