Did you know that they archive the summaries for #langchat (Twitter hashtag)? Here they are in a wiki. So if you miss the chat session, you can read it all here later...
I found this site on Feedly and started following it; this guy travels around the world learning foreign languages; this article in particular discusses how to learn minority and endangered languages, however I find the innovation and his motivation to be the greatest factors in his success. He's not following someone else's path and as the actual process of learning a FL is such a personal thing, I think he's really on to something!
From the site: "There are almost too many sites and resources for big languages like French, Spanish and German. When you're learning a language like these, the problem is usually deciding which resource to use rather than not being able to find one. But what about those of us who want to learn a less popular language (minority or endangered)?"
