I wouldn't say so - as others have noted, there's a few issues that the author of that blog post has with some small assertions made by Matthew Walker. Whether that throws everything in the book into question is an interesting question, but if the whole book was 'complete bullshit' then I'd expect a more comprehensive debunking than that blog post. As to the links you've cited there -- 1 and 3 are the same link (well, HN comments in (1) point to the actual story at (3). The second link seems to agree with -- and be full of exactly the same myth debunking & recommendations that -- Matthew Walker makes. As it happens I'm about 80% the way through the book now.
