indexed

I would've gone with exponential growth. Especially if more than one person is involved in the story-telling.

This graph seems strangely linear, in contrast to most of indexed, and I'd think exponential would be better. Bassically: What's going on?!? ;)

Somewhat related... I heard once that the first time you tell a story that you heard from someone else, you have to say who you heard it from, the second time, you have to say you heard it "somewhere," and the third time, you can claim it as your own... ;)

Strangely, people in my family have a habit of hearing a story, retelling it exactly as is, but claiming it as their own experience...

My dad does that. But denies it. Once he was telling a story to my mom's brother's as if it were he and his brother. They called him on it and could not convince him his version was not the truth. Despite details in the setting which placed it later in time, to their era of misspent youth instead of his.

log-log scale, maybe?
