One request I get a whole lot is to talk about how to learn a language, or one harder, a language using only a book. I could just "talk" about it, but I figure doing it real time might be a lot better. I taught myself Latin this way nearly 10 years ago, and now use my Latin knowledge all the time academically. Part of my knowledge of Chinese also comes from my particular method of learning.
Anyway, I want to record myself going through an introductory language-learning book, verbally externalize my thoughts to make it clear how I interpret what I see. Obviously I have a lot of initial knowledge about languages generally, but as it comes up, I'll mention and explain all the needed concept and why they're relevant.
The language I've chosen to learn is Old Norse/Old Icelandic, which, as it happens, is very close and mutually intelligible with modern Icelandic with some minor differences. WhyOld Norse? (1) It's an ancient language that can be useful for my own understanding of historical linguistics, and the development of Germanic languages, (2) it still has some older linguistic properties that will keep viewers informed of a more highly inflected language, but (3) it also has a vocabulary similar to English, which will minimize the rote memorization aspect of learning it.
The book I'll probably be going through is Old Icelandic: An Introductory Course by Valfells and Cathey. I'll either have a physical copy or a pdf of it, which ever ismore convenient for recording. If you have any other suggestions, feel free to give me them! Again, the point of the series isn't supposed to be just on Old Norse/Icelandic, but on language learning generally, so everyone is welcome to watch! ;-)
