When I am in Realm Chat, I get all the extraneous "World Chat" fluff, too. This does not happen in Guild Chat.
Since you have two different avenues for accessing the different Chats, it would be nice if I set the button to the Left of the Text Entry Box to Realm AND clicked on the Realm Tab, that I would ONLY get Realm Chat. It would make it much easier to carry on Realm conversations (Beta and Zeus (4) are both very good at chatting up Realm partners).
Regards
