Perhaps it's not really relevant, but if it weren't for a failed story that a partner disappeared from, I probably wouldn't have found a second home here, or shared in all the great stories and writing experiences that I've had.
I took the idea that came out of that *poofed* story, and put my own spin on it after a hiatus -- and it was picked up by someone who has been a wonderful writing partner and friend over the 4+ years we've been writing together, and that story is still going on. Not only did he give me a chance, when a matrix might have well 'nixed' me at the time, but he set an example for me of the kind of writing partner that I now strive to be.
No idea is wasted, not really. And a great writing partner for me is not necessarily a great writing partner for someone else. When everyone here is looking for so many different things ... how can you translate that into a formula, other than individually?
When I get frustrated with online writing these days, I just try to think of all the fun I have, and have had, with all the stories that went well, for varying degrees of 'a while', and for the good connections I've made and the ones that are still out there to be made. The partners that communicate with me, even when ending a story, or that are understanding when I need to pull back, are the ones I stay with, will come back to, and hope to write with again -- and recommend to others.
