Messaging paradise is a Real Time and New platform.
According to Ross Mayfield who is a genius, the lore is you can never build
a paradise.
You can only get to it.
Either you make something Old and Real Time them take it to paradise. Or
you make something Asynchronous and New, and take it there.
E.g.
Lower left:
Paper mail
Email
Message boards
Upper right:
Snapchat
Facebook chat
Gtalk
Skype
Yammer?
OK so wait how is Snapchat up there? Well they defied the laws. Maybe
mobile makes it possible. Maybe they were Asynchronous actually. That
exploding feature is kind of unique. Anyway. It proves the rule.
