How Edmodo will make money going forward is not clear. In a conversation with Fast Company, Borg hints at possible revenue streams—for example, by becoming a platform on which other (paid, we assume) applications could sit, or by becoming a channel for educational materials to reach classrooms. Borg says he is looking to Hoffman and Cohler, both veterans of building out vibrant networks, for “insights on how to leverage a massively adopted networked business.”
Sounds cliche, but something like this is long overdue. K-12 education would clearly benefit from the network effects that have made Facebook / Cell Phones / the internet / et cetera such effective tools for distributing and collecting information.
