Well I argue that point.  I love both but I can&#x27;t imagine running the streets of the Arab spring with my laptop, or trying to keep my phone battery going while I maintain my connection to an IRC network.<p>There are some things where the combination of public, easy to use, short, sms friendly are a big plus for some things.  Not that twitter is the only one doing these things or that they couldn&#x27;t be built on ICR.
