I love the colourful diagrapm that accompanies this post. And the content is pretty good too. The authors "focus on how to link multiple online identities of learners and their contributions across several social media platforms in order to study their learning behaviours in open online environments." In the paper (6 page PDF) the authors found that less identity resolution that expected was needed because the participants mainly used Twitter, even when they were taking different courses. This might be one of those results that needs more study, because while the educational community uses Twitter a lot, the network is less pervasive in other communities.
