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!
