This one's already made the rounds, but it seems pretty solid and worth keeping: Distance Learning – Social Software’s Killer Ap?. Cool that they're using Elgg for this Athabasca pilot program, but I'm still not really clear exactly what they're trying to do. It seems that the expectation is that it will be used voluntarily for "optional" educational tasks, in the context of programs at the university (only open to registered students). What would be the incentive for students to use it if it's optional?
As I was writing this post, Dave pointed me to Scott Leslie's take on it, which clarifies it -- I'm looking forward to hearing about the project as it develops.
