In all seriousness, it's probably just that we see the DoE's and then rarely see any disbandment notices (for obvious reasons). It's not a major problem for me, but I do feel sometimes it's a bit of a shame when new players join up in a friend's mirco alliance, and then when that folds they don't stick with CN at all. However we have to remember that new alliances do tend to bring in new players to CN (and some do stay), so that's gotta be a good thing.
