Joe is trying now to avoid posting unconfirmed news and fakes & theories, excepting CoroCoro leaks... but, with all my respects for him, he has a past!
I am reading Serebii since 2004 and I think he did and he is still doing a great job (even with that old-looking website), but I remember how he posted fakes and confirmed things that later weren't true. So I don't understand why is he trying so hard to discredit PokeJungle for doing that.
PokeBeach also stopped covering rumours... and I think that we need a community where we can talk openly about them and discus them.
Paul's website (PokeJungle) does not pretend to be a
Serebii.net, it's just a blog of Pokemon news and thanks god that someone is covering rumours with that entuthiasm because, come on, we all like to talk about our theories and speculate.
Someone will say that Serebii Forums is also another place for talking about rumours... but it is not a website as accessible / modern as PokeJungle, that's why I never used it.
