I think one area where a learner's social network can help is to pick formal training programs. Many organizations have hundreds of courses listed in a formal learning management system, where those courses languish without anyone looking at them. Those course lists can be selectively surfaced in an appropriate place where learners can see who took the course and what they said about the course. That, I think, is a meaningful way to provide value to learners using their social network. Social learning platforms should be to formal training catalogs, what Yelp is to restaurants.
What do you think?
