What makes a guild "good"?

Eh, I suppose a "good" guild is one where the members getting along/know each other, and some occasional guild activies (bossing, GPQ, and I guess maybe some random quizzes? One of my oldest guilds had these). Most of the people in my guild seem to get along, although we are lacking GPQ. I, as well as other juniors can't seem to find the time to do this. :|
