You're right. I lurk like crazy , but don't really submit other than the one. It's just that everything else I go to submit is always already submitted. Perhaps I just a little behind in finding links. I'm not much of a commenter, since I don't really ever feel like I have anything of value to say. Maybe I need to just try.
I appreciate you pointing it out - I'd like to try to contribute in a positive way, I just need to try to dig up interesting things before everyone else!
You don't have to submit stories to be part of the community, lots of people blog and submit their own writings but it's a smaller part of why they're here.
