Looking at the tags into detail:
- They don't group all the questions that should belong to them.
- Their statistics don't make sense, they are both less popular than command-line.
- They have no additional value when searching, as you would look for more specific things.
Looking at the questions tagged into detail:
- It's clear from the other tags and title if the question is about hardware or software.
- It's very weird to add software next to windows-7 or hardware to cpu.
- There is no single question that actually needs the tag.
If the tag can’t work as the only tag on a question, it’s probably a meta-tag.
If a question was tagged software, we have to wonder about what software. Check!
If a question was tagged hardware, we have to wonder about what hardware. Check!
If the tag commonly means different things to different people, it’s probably a meta-tag.
What software are you thinking about? Or what hardware? Check!
The problem is that these "meta" tags cover "all" questions on the site, while there isn't a single question that needs such a tag. Can anyone give sufficient counter-examples? From a software engineering perspective, these tags are like god classes while they better fit to be used in the form of the mediator pattern (thus in the form of tag sets).
