I think there's something in the game helpfiles about how to play the game or something that says that it's best not to speed-play. I am actually not sure if this was in this MUDs helpfile or another one, but it seems like it was for newbies.
Basically it said that there's no point in conversing and answering as fast as you can, that it's better to consider what someone's said and take some time to think of a thoughtful response.
I think it everyone did this, some things might be easier. But...I am VERY guilty of typing out long responses and sometimes responding pretty quickly. Usually if I am talking with someone I TRY to stay focused on that conversation, and TRY to allow the person to respond before moving on. Of course, as has been said a few times already, mass discussions can become much more difficult. I don't think there is much that can be done about that.
Other than maybe just make your character reference back to something that might have been said several sentences ago to make sure your valuable input gets transmitted to us, the other players!
Also, I often handle talking on top of each other like Zheren does, with it basically being like I was interrupted and then responding as if cut off. I think that's a good way to start out writing your idea without deleting all the text and also make it seem a bit more dynamic. Even though it might then make it seem like Geas is a very rude world where everyone just interrupts each other.
Hey, it's a cultural thing.
