How big is your guild? Do you know everyone in it? Do you make an effort to really know everyone in it? Or are you content to surround yourself in the people you know and ignore the other 200?
Just this discussion came up the other day amongst my guild-mates and I and I genuinely think that it needs some serious thought if a large guild is to be successful. It is a natural human trait to form a small group of people around you whom you really know well—you might consider these your best friends. Sure, you will have other friends, beyond that acquaintances and everyone is different; one person may maintain a very small circle of close friends where others will have much larger groups. At some point though the guild grows beyond the size of even the socialites largest circle and that, in my opinion, is when issues arise.
