Well...obviously we copied (directly ripped off) reddit, but we sort of see headcycle as "the grown up version".
Both of these probably would increase traffic...so it's a thought.
Edit: Ask and you shall receive.
Also, there's a bug in the code to create a headcycle - so thanks for uncovering that.
Should we add these headcycles to the list? Unfortunately I can't add anymore headcycles but I did add a headcycle for heavy metal music, female metalheads, and the show Stranger Things.
