I can see that this would be a useful tool for projects such as these Things. Someone's having trouble doing something and posts a question. Someone else posts an answer. A way to provide long-distance support.
Could this be used in a library setting, for library users? Maybe in a reading program that had activities and projects? Or some kind of writing workshops/classes?
This may be a Thing I don't use much, but I can see there are some real-life applications.
