I speak (some) Chinese, but I've always had a problem with remembering tones. So I found a list of characters sorted by frequency, wrote a python script to parse it and massage it a bit to generate an anki deck of "character -> pronunciation (definition)" mappings (and for characters that have several pronunciation, it's "character (definition) -> pronunciation"; so far I've been reviewing that deck for the past couple of months, but as it has several thousand entries it'll be years before I'm done with it (if I feel like it's getting old I'll stop reviewing it). When I encounter a character I don't know how to write I also add it back as a separate entry in another deck.
For studying German and Japanese, I have a Grooveshark playlist with a few Disney songs, and I also have some google docs with the lyrics which I occasionally read/try to translate (I haven't put much time in this apart from listening to the songs while I work; I haven't entered anything into Anki yet).
We used to have a regular German lunch on thursday at work, but the organizers quit and nobody picked up; I would usually add a few entries to Anki each time (and I still review them). I might organize a Japanese lunch eventually.
I have a "Mafalda" comic book in Spanish in the restroom, along with a Spanish-French dictionary, and usually read one strip (looking up unknown words) each time. Nothing in Anki, and I don't study any Spanish outside of that.
This is a thread to connect rationalists who are learning the same thing, so they can cooperate.
The "learning" doesn't necessarily mean "I am reading a textbook / learning an online course right now". It can be something you are interested in long-term, and still want to learn more.
Rules:
Top-level comments contain only the topic to learn. (Plus one comment for "meta" debate.) Only one topic per comment, for easier search. Try to find a reasonable level of specificity: too narrow topic means less people; too wide topic means more people who actually are interested in something different than you are.
Use the second-level comments if you are learning that topic. (Or if you are going to learn it now, not merely in the far future.) Technically, "me too" is okay in this thread, but providing more info is probably more useful. For example: What are you focusing on? What learning materials you use? What is your goal?
Third- and deeper-level comments, that's debate as usual.
