Ideal digital learning communities have a collaborative platform, appeals to many types of users, and focuses on a topic or closely related topics that bring users together. In my research, Brainly, what was OpenStudy, provides a place for students and moderators to help with homework questions. Users also earn points by helping others with step by step explanations. It has a huge, world-wide social learning network with a list of well-known supporters listed on their website like Open Courseware, NYU, CNN, and Georgia Research Alliance.
I made an account to see how it was up and it organizes itself as a question/answer service where you can earn badges and points for answering a certain number of questions in a certain amount of time. Users can filter the forum based on subject area, school level, and completion status. Another key component is that they have a social presence in which they have live posts. Finally, they have created an app for both apple and google.
I've included a video of Brainly's introduction along with some other impressive digital learning communities.
