I was recently searching for tags consisting of only one or two characters. I assumed that since these don't show up in search suggestions, there would only be a handful of them, and most should be eliminated. I eventually realised that my assumption was wrong, that I was in way over my head, and that I was acting on a personal opinion that could easily be disgreed with. Thus, I stopped.
In the course of this journey, I discovered many 'number-only' tags. Instead of blundering forwards on my own again, I have decided to do what I should have done before, and ask for input on these two questions:
Should there be tags which are only numbers?
That is, should there be tags which consist only of a string of digits and nothing else? For examples, take the artist tag 87, and the character tag 31. Should these be 87_(artist) and 31_(character) (or similar) instead? Number-only tags feel somehow 'too ambiguous' for me, but I would be interested in other opinions.
Many of the number-only tags I found were general tags used on posts where that number appeared. This prompted me to wonder:
Should there be tags for specific numbers which appear in an image?
I feel that certain examples are justifiable, such as 69_(number). However, I am less enthusiastic about tags being created for every number which happens to appear in an image:
1_(number), 2_(number), 3_(number), and so on to infinity.
The purpose of tags is to enable users of the site to find what they want to see (and to not find what they don't want to see). Take post #2379867 as an example. If someone remembers this image and wants to find it, would the existence of a 42_(number) tag be helpful for them? What if a post is the only image on the site to contain a certain number; would the number tag still be justified if it is only used once?
I would like to make clear that this second question is about tags for specific numbers. Tags about numbers in general, such as phone_number, seem fine to me.
I would be very grateful for anyone's thoughts on these subjects.
