We have multiple tags for the various models of the Raspberry Pi: model-a, pi1, pib+, pi2, and pi-zero
And two related tags: models and raspberry-pi-foundation
As you can see, there are differences in hyphens, whether it says model or pi, etc. To make them consistent, I recommend these renames/retags:
pi-zero > pi-zero (to stick with official naming and keep it the same)
pi1 (only has 11 questions, so should retag to specific models)
> pi-b
> pi-a+\
raspberry-pi-foundation > pi-foundation (I created this tag for two specific questions; however it has been frequently misused (presumably) because it is the only tag with the full word 'raspberry' in it. By renaming it, it will be pushed below the model tags in search and hopefully not abused)
This means we will end up with:
pi-a, pi-b, pi-a+, pi-b+, pi-zero, pi-2
And: pi-models, pi-foundation
Optionally we can add raspberry-
to the start of every tag for better searchablility.
