are there some popular community ingame hangouts outside of cities?
It isn't really one, but Zelechor Hot Springs should be one.
It's not a consistent spot but there's usually a crowd at the end of the daily jumping puzzle or mini dungeon. Mesmers will stay there to help people through it, but there always seems to be other people hanging around too.

"You can run like a river, Till you end up in the sea
And you run till night is black, And keep on going in your dreams
And you know all the long while, It's the journey that you seek
It's the miles of moving forward, With the wind beneath your wings"
Farming spots..... always with the farming spots
sure, any wvw garrison will do. Slackers hang out there, keeping those who would love to get in and fight in the q.
