I did find a list that specifies how tags should be used, found here. However, I did not seem to find it explicit on how we should format new tags to make sure many duplicates are not created.
In the case I have now, I would like to create a tag for Go-Karting. Should we be using hyphens where they are used in the spelling of the word, or should we avoid them in case someone misspells words? How about for words such as Go-Karting or Go-Kart which are commonly referred to as Karting or Kart. Should we use these abbreviated terms, or is it in the best interest of the community to keep the original word?
