Language education site Busuu emphasises the social side of learning a language. While Busuu has standard components such as vocabulary exercises with audio and writing units to test out your composition, the most interesting aspect is its ability to connect you with both people learning your language and native speakers of your language. You're learning Spanish and someone else is learning English? Connect through Busuu and help each other out. While Busuu may not be a substitute for the do-or-die learning of full language immersion, it has a wider range of tools and social interaction than a standalone program or book.
