"The client needs to maintain an active connection at all times" is just plain wrong. Offline messaging is what makes it so much more fit for the masses compared to IRC (I adore IRC btw).
I don't mean offline messaging with messages waiting for the user to go online. I mean the lack of push messaging capabilities, so the user/client doesn't know there is a message waiting until they already go "fully" online.
