I don't participate in the fandom much, other than reading EQD and posting on these forums every now and then, but I, like you of course, have noticed the craziness (duh). But, as it has been said countless times above, this is a (sadly) normal thing, especially for huge fandoms like this. With such a wide array of people who've put their faith in the show, it's easy for things to get out of hand and for members of the community to, per se, freak out. But rest assured, this is just a phase, and all will return to normal shortly.
Or longer than shortly.
Whatever. Either way, I am one of the people who isn't freaking out and never really has. I just watch the freaking out and roll my eyes, but in my head, because I barely ever roll my eyes over anything in real life... only in my head. Anyways...

Do the thing of which is the opposite of a frown!
