Ultimately, Amiga.org is tops; outside of that...eab.
Most of the folks who post here and at eab aren't suffering under any delusion that Hyperion will be worth $50m in five years or that any day now the world will embrace poor old creaky Amiga OS (or Morphos, or AROS etc.) and en masse abandon Apple, Windows or any of the dozen or so supported OS choices out there.
IOW, they use the Amiga for fun, which considering the hobby niche is really what it should be about. Like the guys who push A600's to the max - they don't honestly think "Well this is a better general computing platform that an equally equipped Mac or PC of the same vintage treated to the same types of upgrades". They do it because it's fun.
