Currently running the program. It's beautiful to look at and starts of with teaching Hiragana and mixing it with some History/Geography then continues onwards. I haven't came that far yet (started with Katakana as of tonight) and I haven't tried any other "study site" but I think Human Japanese looks like a good product.
It's a free trial with no time limitation that is free until Chapter 13.
