[Mailman-Users] users object to [listname] prefix

I just switched our internal lists over to Mailman (yay!!!!) without making an announcement on the list. The switch went smoothly, once I figured out how to get the old archives into mbox format!

There are now a lot of messages on the list, however, objecting to the [listname] prefix taking up "valuable subject line space". I suspect all of these people are using Microsoft products... anyway, has anyone else had this experience? Has anyone explicitly commended the use of the [listname] prefix? I personally like it, and don't want to change anything. The list has ~500 subscribers, and 5 have so far complained. I could just ignore them... any thoughts?
