Is it still popular?
Whenever I see advice about learning kanji, I think about the book Remembering the Kanji. When I was living in Japan, it seemed like everyone who wanted to learn how to read Japanese had that book. I bought it, too, but I didn't finish reading it. I wonder how many people nowadays have that book, or if it's as popular as it used to be. It seems like a book that people buy, but don't finish.
