Well, I've been doing so for all of them in the hopes that the others who have participated in the past or new people will join in the fun, even if one day, I'm no longer around (No one knows when it's their time to go - A person can be crossing the street one day and then suddenly get hit and killed by a drunk driver). In theory, these Three Words games can continue on without end (Story arcs may end but new story arcs may arise afterwards just as in manga and anime series like Bleach) as long as people in the community share in the creation of the "Stone Soup" ->
