I'm just starting out. Anybody have experience with TextFugu? The way the lessons are presented it looks pretty solid.
I'm still just learning the basics of Japanese (and have taken a hiatus for my other studies) but It's the most solid thing I have seen for learning. It's more of a backbone to your learning. Use it as your primary path through the language, it acts as a friend and guide for both knowledge and learning technique.
The program has wonderful pacing, and has you learn certain things (like hiragana) before moving on to other things. It doesn't let you get ahead of yourself, and forces you to learn the hard way.
That being said, you eventually should augment with other sources as your hunger for learning grows. But use it as your main companion, it really offers the best approach for independent study that I have seen.
