Oh, I misread your comment, I think. You're talking about the showrunners themselves incorporating ideas from the community, right?
That would be great, although unfortunately Hollywood is so concerned about lawsuits that show staffs aren't even allowed to read scripts for their own shows. For example, the Silicon Valley staff isn't allowed to read this script; if I wanted to apply for a job there, I'd have to write a script for a different show and send that in.
