After the Why We Sleep fiasco I'd quite like a site which peer reviews all the references in a book (could be crowd sourced wiki-style) individually. And then the book, or each chapter, gets a rating for factual correctness.

In hindsight some of the claims are just weird, like saying you can measure the effect of one bad night's sleep months down the line.
On the whole it got people talking about sleep, which isn't a bad thing. But, the peer review (see sibling posts) only looked at one chapter I think, so God knows what else is wrong.
I don't think anyone is doubting that you should probably get a bit more sleep, try not to blast blue lights in your face and get into a routine. Standard sleep hygiene stuff.
