"One of the most interesting things I noted from the recent developers presentation of Google Wave was that they have built in functionality that allows you to start generating a response before the person you're communicating with has actually finished their reply.
This effectively replicates one of the least useful characteristics of human communication i.e. a speedy response rather than a considered one, that takes into account what has been communicated, not what you think is going to be communicated."
Reminded me of this quote that I really liked in Herd:
Just one of things that you never really thought about, but when someone points out creates a little spark.
