15 years ago I thought that we are soon going to use our communication tools in an informed manner - what needs synchronicity will be done on IMs, what is more conversational, but not synchronous, will stay email, things that are more contextual will move to wikis, we'll have general pub-sub infrastructure where the sender and the receiver would have means to negotiate what gets through. But now I learned that channel stickiness is much bigger than I thought.
