It's clear to me that virtually everybody on this board who posts insider information talks to important people. That includes Chief, who despite the persona, is likely pretty plugged in. It also includes Oz who went from infallible to a punchline within a four month span. Talk about fluid.
Zion clearly talks to a different source than the one Chief and Oz have talked to. If that makes him more reliable, that's fair. Ultimately, you're either right or you're wrong - it doesn't matter if you're Bob Woodward when you're wrong.
Maybe I'm just gullible and some of these guys are laughing behind their computers, but I don't get that sense. Gun to my head 99 is my favorite insider because he's the only one who's not self-aggrandizing about it.
