I would like to pose that yes, the current situation isn't ideal but, bar a little tidy up, it's okay.
Here's how I see it: Tags are useful in a number of ways, primarily around filtering content. I can subscribe to a tag, or filter it out, or make it a favourite. For this reason, tags should aim to cater to areas of expertise.
Minecraft is a pretty special case amongst games given the enormous breadth and depth of mods out there, and the extensive modding community. Not to mention minecraft is the biggest tag on the site. Feed the Beast and other modpacks are made wildly popular by channels such as the Yogscast. Clearly these are things people want to search by, filter by etc.
I propose the following loose guidelines:
- Remove minecraft-mods. I can't think of a good reason for this to exist (although if someone can suggest a question that is about mods in general where this might be appropriate I'm happy to change my mind)
- Tag mods as we do, e.g. minecraft-buildcraft
- Tag modpacks as we do too, e.g. minecraft-feedthebeast
- Use all appropriate tags for a question.
These feels kinda icky because we're used to having only one tag on a question at any one time, and having 3 or 4 feels a bit wrong, but I believe in this case it's justified.
