Your best A2A friends are going to be the ones who can provide you with both strategy and encouragement. They show both intelligence and encouragement beyond merely commenting in the forum. You can gauge this best by directly engaging people on the forum. Follow those who seem to give you insight into SFI and seem willing to invest a little attention and encouragement in you because those are the ones who really want to see you succeed. Those are critical values in an A2A friend.
