Usually only a handful of people see any real difference and many get quite passionate about the fact that they can have great conversations with people online or by email and even texting.
I am not so sure. To me face to face conversation is so different to computer mediated conversation that I always say that "real conversation" can only take place face to face.
Yes, am aware I am playing with the definition and accepted use of words here. Conversation is always going to be the everyday term for conversation however mediated.
As part of the resources I am pulling together for a future book on conversation I have bookmarked this blog post from Chris Rodgers whether he says that Theres no such thing as on-line conversation that "Conversation is an ongoing, 'real-time' exchange" and that "Conversations are spontaneous and emergent, not planned and structured".
I could not agree more.
And, oh yes, when people ask me if you can run Knowledge Cafes online. I say "Yes, but it is so different you can no longer call it a Knowledge Cafe!"
