Looks good, very easy to follow (I normally get the urge to swap to another firefox tab during slideshares). I find that the 'micro-blogging' terminology bewilders some people and that it's often best to jump straight to 'status updates' (most people seem happy to accept the benefits of 'status updates' & regular contact with other people); have you noticed this at all? I probably wouldn't be too tough on the idea of 'broadcasting', though; the top twitter users are probably doing just that and paying very little attention to @replies.
It's definitely getting there. I quoted some more Hugh MaCleod brilliance, plus some other research that you might find useful here:http://lukebj.blogspot.com/2008/11/how-social-networks-work-object-centred.html
