I think there are 3 types of alliances... (this is the shortened version since I don't remember everything I posted the first time).
1) Thread Alliances: These are regular 'real' alliances. Ex: DMCA & MISE (or whatever the college one is)
2) Fake Alliances: These are created more as inside jokes. They may or may not have a thread. Ex: Mad Cow Alliance & Cult of Gurgi
3) Groups: These aren't alliances at all, but rather a group of people who have the same feeling towards something. Ex: FOCM & MC Hurricane Alliance
#2 &3 aren't bad since they are either short lived or do not have threads
#1 can be the pesky one. However, I don't think they degrade Micechat. All but one alliance only requires a person to post in the thread to be a part of it (exception being COW). Anyone can join these threads very easily (especially the more random ones). I think the first time I posted this it sounded much better. I know I'm missing something this time around. Oh well.

Hmph, my post was lost in the server downtime, but here goes my post again...
I might be a big hypocrite for saying this, because I helped create the Awesome Club. But that thing is as dead as my attempts to get a life. I am getting a bit tired of seeing a ton of random alliances sprout all over the place.
