I love Wikipedia. I love gathering learning content from many sources, but Wikipedia is my favorite: it’s got many aspects and features that I (as well as many other people) look for in an online learning tool: the learning content is well organized, categorized, user-generated, collaborative, and so on.

But wouldn’t videos make Wikipedia even more engaging? What if readers and editors could leave comments on the learning content, and those comments were categorized and organized so readers wouldn’t have to trudge through heaps of misspelled rants? What about a chat feature? Imagine being able to exchange opinions (and questions, why not?) with someone who is on the same page you are, right that minute?

Wikipedia is a fascinating foundation for learning content—receiving it, generating it, and perhaps even actively exchanging it. What else is missing?
