If I make a post and my gang sees it, then attempts to relay a new set of information a few hours later is basically futile through the use of the edit button. There is no inclination for members to check the thread again when the last post has already been seen. No notifications through subscriptions either. Additionally a few others members could start a discussion below it before the members who previously saw your post get a chance to see the edit. You could argue much of this holds true for all sections on the site. Unlike other sections of the site though, these threads mainly serve the purpose of being a discussion area for members of the gang as well as other associated users. Having instances where new gang information or discussion may be unseen by certain members is very counter to that.
Considering the above points and the fact that the vast majority of activity within a gang thread comes from members of the gang itself, I think this exception should be made.
