A year before I was born :)
I tried reading the book a few years ago, I remember being irritated by the QA style it uses and dumping it because of it. On my second attempt I realized that it's only irritating if you know the answers very well and skipped to the chapter I didn't have so much confidence in understanding. And it was very pleasant experience, especially when I stopped to think a little before reading the answers. It felt like I was having fun.
So I'd advise to give a book a go, even if you are confident in your Scheme and FP skills. Just skip the parts which seem too obvious to you and get to the interesting stuff, you won't be disappointed.
Now it's time for The Seasoned Schemer, I guess :)
