As it turned out, this was one of the best courses, online or onsite, I have ever taught. Not only did I witness enormous engagement among almost all of the students, but the level of learning was much higher than in previous years.

The feedback from the students on the course was very positive, better than I had received for the onsite course in previous years. One of my favorite written student comments was, "… I don't know how this course could be taught as effectively in the classroom."

The 90-9-1 theory explains the percentage of a wiki's participation, breaking it down as readers being the highest percent, with minor contributors composing the 9 percent and enthusiastic and active contributors composing 1 percent of the total participants in a wiki.

While it is impossible to overcome this type of human behaviour, it is possible to change the participation distribution (i.e 80-16-4 where 80% are lurkers, 16% contribute a little and 4% contribute the most).
