EAB has less noise, but it has a lot less signal too. you make a query here, and you'll get multipe answers within half an hour. EAB post rate is a lot slower. besides, they are not mutually exclusive. you can be a member of as many amiga sites as you like. if those who have left just waited, things would have calmed down again, this sort of thing has happened multiple times before, and it always gets back to an even keel.
