A common pattern of subreddit nomenclature on Reddit is the anarchy of naming subtopics (like Game memes, political memes).

e.g There are multiple subreddits for TF2: r/tf2 and r/truetf2; however this is confusing. These

I think there should be tree-style communities; it probably won't stick though.

Examples:

  • !tf2/memes
  • !communism/memes
  • !vexillology/help
  • !vexillography/memes
  • !linux/memes
  • !videos/meta

(I wouldn’t use backslashes; since they are used in URLs.)

(I don’t see much reason to agree with this suggestion; but some other people might be able to agree with it.)
