I'll tell you what would be awesome. A peer reviewed hacker reading list. But, only the really sacred books. For instance GEB or from the post that prompted this post, after reading that review, I can tell you it will absolutely be my next non-fiction book. I've been wanting to read through some old textbooks to try and pick up somewhere I might've left off, but always found them distancing. This looks like a great way to dive back into it.
Someone want to hack it together? Maybe have a vote site built similar to YC/reddit where anyone can submit a book and discuss it, then the most popular submission every 2 weeks is chosen and we all read it?
Maybe decide 5 groups of books (business, technology, scifi, philosophy, etc) and choose 1 from each every month, to facilitate those who may want to use this book club for different reasons such as a learning facility (those who would gravitate to functional books on tech for example) or an escape from the every day (and read/discuss scifi or philosophy). I don't know, I havn't really thought this out. Maybe I'm over complicating it - I do that when I'm boozy!
Either way, it sounds like it could be a fun way to play with the Amazon API.
