First of all, I spend far too much time there.
Second, they argue about everything there. I suspect the more mature people are clashing with the less mature people. Things used to be better there, but since the storyline hasn't been giving back much payoff I methinks the folks aren't taking to kindly to the non-answers.
And by non-answer I mean
How is Ruby a demon if she remembers being human?
How is it okay that Sam is sleeping with her? I try to get past it. I can't.
Why did the angels wait so damned long to save Dean?
Things I DO NOT want to happen on Supernatural
Anna to come back pregnant...
There to be another Winchester relative
