Autodidactism is the practice of teaching oneself. Benjamin Franklin is the classic example of a self-taught scholar. In today’s age of ubiquitous knowledge, being able to teach yourself quickly is just as useful as being intelligent, given the rate at which technology, information, and interactions change. If you’re interested in becoming an autodidact, or self-teacher, here are a handful of websites that can supplement your learning.

Duolingo is a website to help people pick up another language. Currently, they boast choices ranging from Spanish and Danish to Portuguese and German (for English Speakers). They offer services to help people learn English as a Second Language also. The Duolingo website is centered around immersion style questions that require listening, writing, and speaking (optional though). There are question forums as well, and the website layout is such that Duolingo feels more like a game and less like an online course. The best part, is that Duolingo is completely free.
