Well, that's what 'not take part in an existing system' stands for. If you want to be outside a social system, that can be your choice. If not, then you'll have to deal with all of the constraints. That could be ICQ vs. MSN vs. AIM vs. YIM or BBM vs SMS or now iMessage vs. WhatEver.
The mass consumer market won't all join IRC to chat, they could have (and still can) for decades and it just isn't happening. And that's fine, but that also means that other systems (like iMessage but also Facebook) gain users with all the lock-in that comes with that.
