I'd consult goodreads.com (ownded by Amazon) to meet your criteria of matching experience with respect to genuine reviews, similar book recommendations, etc.
It's not a flashy service by all means and has definitely been neglected by Amazon since the acquisition; the community makes it what it is, and it is a very high quality community!
I've read that Goodreads has kind of an opposite problem to shill reviews: everything you write about a book is always completely public, so people don't write them.
