If you accept that Learning is a Conversation, and that some of the most powerful learning can take place in the process of conversing and exchanging ideas with others, then setting up ways to have as many of these conversations as possible seems like an obvious thing to do.

It might be easy to think that the people on the stage at conferences have the knowledge and that if we simply listen to them we will get wisdom, but the truth is that sometimes it just doesn't work like that, and even if it does, most of those ideas gather far more momentum once we start to internalise them through further conversation with others. Ideas beget ideas, one thing leads to another, and you often find some of the best, most useful ideas come to you not from what was said by a speaker, but from things that came to to you as a result of further conversation about what was said.  (by the way, the same logic applies in classrooms too!)

If we limit our notion of learning to the "official" channel - the teacher, the textbook, the syllabus - we miss so much. Yes, learning happens at school, but what about outside school? Yes, learning happens in the classroom, but what about outside the classroom? Yes, learning happens in the act of "being taught", but what about when we are not "being taught"?
