Zero creativity? That's offering me a false choice. I think they've got some midiclorines...hust not enough to be a Jedi. Hotel California is monumental. I think it's beyond the talents of those you mentioned.

You put me in an awkward position of using myself as an example. But if everyone on JPF was equally talented, I wouldn't have been easy to spot, I would have blended in.
The fact is, these sites aren't as popular as they once were
and several have shut down. Not everyone can write or compose. Many can mimic the mechanics. But they produce the same work in 2018 that they did 1998. The sites stagnated and dwindled.

My views on talent and creativity just aren't that important.
People would be much better off demonstrating creativity
than arguing about who has it and why.
