Interesting point made by Melissa Emler here. I am thinking more about online communities here just like Stephen Downes (I found this post in his newsletter) thinking that maybe event is the most tricky one to organize in the sense that it is synchronous and therefore, more vulnerable. Also, I am thinking if community is equal to the other two or also a goal in itself: Emler says that without a community there is no sense-making. True, but a strong community is also needed for further learning, its being perhaps the only thing that not only instigates motivation towards learning but also feeds learning with more content.
