You write that "One way to help readers learn is to enable them to interact with content and each other on Wikipedia". Is there evidence-based research that suggests that this is so? In other words,before you ask ''How'', should you not make clear ''Why''?
I also note with concern that interaction with content is packaged into the same sentence as interaction with other readers. There seems to be a trend to try to turn Wikipedia into a social networking site. This did not go down well when the Gather project was launched, as the community of content contributors pointed out that their current policy is that Wikipedia is not a social networking site. Would it not be a good idea to resolve this contradiction first?
