How come then we don't have the variety tag?
- Just "variety" is too vague
The word primarily means http://www.vocabulary.com/dictionary/variety
Variety can also describe different things that are classified under one category or type
I didn't know the variety wallpaper changer app before you mentioned it.
It would be missused in a variety of ways.
There is a total of 17 questions for searching "variety wallpaper" https://askubuntu.com/search?q=variety+wallpaper
Not every app should have it's own tag.
If there is a bug with the app - it should be reported to launchpad.
The scope of the tag is limited to two or three questions in the search for "variety wallpaper" aka - we would not tag a question about wallpaper with the app that is a possible answer.
That is one of the tags where the real name collides with some generic term, and since I love making people read unrelated examples, lets read the case of the [pig] tag:
pig /pig/ noun
noun: pig; plural noun: pigs
- an omnivorous domesticated hoofed mammal with sparse bristly hair and a flat snout for rooting in the soil, kept for its meat.* synonyms: hog, boar, sow, porker, swine, piglet
- an oblong mass of iron or lead from a smelting furnace.*
- platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs.
Problems with the tag: when asking about analyzing some pig epidemic data array the sistem suggest to use the tag. Relevant example: The pig question
Solution: Rename to apache-pig to prevent confusion
* Thanks to Google
Now, the reason to create a tag is: there are experts in questions about variety? If the answer is "yes" then create a tag that is: one, easily recognizable for experts and askers, two, unique, three, isn't render for abuse or confusion, four, there are enough questions base that warrants a tag.
If you will tell me: but look there's X tag, and nobody seems to have problem with it, why this have? I will tell you: thanks, that was in the list already or I just have added that one in the list.
As hbdgaf points we don't need a tag for each and every application available for Linux.
