I do the same thing! Though I haven't seen any other hedgies near me, I am always worried when other people jump into things and get pets without the proper knowledge. (For example, I saw a young couple buy several bearded dragons at Petco recently, after simply seeing "how cute they were" Ugh!!!
) I think the hedgie and the new owners would appreciate it if you mentioned HHC to them and offered to help get the newcomer set up.
