There is absolutely no issue with people creating their own Gists, in fact--I would encourage it. I believe the idea is that somewhere down the road writers could submit their own gists for inclusion in future collections. And there would be a Dramatica Story Expert or two who could look over the list and make sure it doesn't veer too far in the wrong direction.
That said, if you veer off in the wrong direction, I think if you are consistent with being off track the storyform will still read the same. In other words, if you are consistently inaccurate with the same datapoint the storyform will still work.
I had a notion to start creating a place where writers could upload their ideas for Gists. If everyone is still interested, we could look into it.
And @bobRaskoph I want to see what you've constructed!
