A tentative suggestion.

[Aaronock]

If I want to chat with a bunch of people at once in a shared environment I always used Guild Chat, Party Chat, or made do with Skype/Mumble/other programs of the like.

To me, @main is just like world chats in other games, they are there to announce junk like guild recruitment and stuff you be tryin' to sell. Occasionally you use it to get help or to catch up with other players.

Edit: I missed a word in there somehow grammatically and it bothered me too much. <_>
