It would be really if you added the feature of chat just like on Facebook, where as you can know who of your friends are online and be able to chat with them about anything. Of course we have PM which is good for if you are offline and someone wants to contact you, but that you never know when you will get a message back. I think this is a good idea for each user to keep in touch with their friends on MDL. ^~^
