The biggest Language Learning Community in the World is…

Facebook itself does not seem like wanting to extend its core application beyond the normal web use cases - email, search, connections, communication and address book. Events and photos are two applications they have written themselves. Hence, the language learning community at Facebook would most likely be an application implemented either through Facebook Connect or on Facebook. Now, unless this application has a strong viral component - it would do exceedingly well to pass the 10% test.

10% of all Facebook users will bother finding out about learning a new language - 30 million
10% of these users will be interested in the app - 3 million
10% of these users will install the app - 300,000

This number will be 600,000 if anywhere in the above funnel you consider conversions that are more than 10% - which very very few applications in Facebook [or anywhere on the web] have managed to do. Also, this number [which a successful app would be able to manage] is broadly an average where all social learning networks are - LiveMocha is much more already.

Having said that, I do agree that eventually each of the social learning networks, will need to incorporate a Facebook strategy in their business. With Facebook coming up with a currency of its own and users getting added at breakneck speed - no one can ignore it. There is a definite chance of a killer app in education gaining a lot of ground on Facebook - soon!

Maybe even a virtual classroom? ;)

That's the beauty of Facebook. They deliver the platform and the rest comes from external developers. Plus Facebook users are most likely real users because of the one person, one account rule. There are exceptions of course but compared to other networks the percentage of double and fake accounts should be much lower.

Well done Facebook. Where will it all lead I wonder.
