Eh, I don't see how, but nor do I have the insight of other places it does work, so I can't tell you anything factually.
I actually hate that community, but to each their own I guess. But I also think it's easier to discuss music than songwriting all the time. I personally could discuss music all the time and get a community out of that, and I do do that, but I find it much more difficult to do the same for S&L. It's your call though as you run the show, and I won't contest it more because I know I won't change your mind.
