If life is one big conversation - I'd say that anything that helps us find ways to have a more true, deeper conversation that enables us to see and hear each other better - well bring it on!

this is pretty cool, the only thing is that there seams to be no offline equivalent to it. This should be supported by some kind of pop3 (or maybe a new protocol). I'm still totally against, online all the time, because it makes us very vulnerable.
