Harold, love to discuss this at TK2007. Hope we can rope in a few other interesting folks as well for drinks/dinner or something like that.

Joan - much appreciate the links. It makes a lot of sense to me to use Elgg as part of a collaborative learning experience as you've described. I was thinking more in the context of how I would use it for my own learning? Or in a corporate learning context? Again, makes sense for learner collaboration - but I've not see much use for on-going personal learning.

Again, I may be missing something. Hopefully Harold can shed light at TK2007.
