Scanning this 998-word essay, I'm wondering if OP accepted a dare to write at length about the current state of book reviewing without ever mentioning Goodreads. His essay proves that it can be done, but -- wow! -- what an omission.
Yes, the caliber of reader reviews on Goodreads is all over the map. But it is huge, passionate forum for active readers of all stripes. Spend a little time with lists, filters, reading circles, etc. -- and you can semi-reliably get both reviews and recommendations that are well worth the time invested. Most major publishing houses know this, accept it, and have even come to appreciate it.
As a hardcover author in 2017, I found that my publisher's marketing/publicity team was very comfortable with Goodreads' prominence and felt that its review-by-review quirks balanced out over time in a way that ultimately was quite good for promoting wider readership of interesting books.
