My two cents:
I agree with Holy Star saying, "...no, they eventually spread their wings and fly away!".
This is exactly what happened with me.
I used to be a active member of Pokebeach, back when I was starting to get into competitive play, I was like that for about 2 months.
Then I found the 'Gym, and migrated to here.
In doing so, I 'left' Pokebeach, but as a pokemon newbie, Pokebeach really helped me in learning the lingo and metagame stuff.
So imho, Pokebeach is great for newbies, when they learn and find out about all the important things about Pokemon, the 'fly away' to Pokegym.
I find it very unnecessary for HS to hack pokebeach. I don't see any real point, other then to act out and get attention.
JMHO.
