I don't really understand the sentiment in the article about Amazon not doing anything with it. When Goodreads was acquired, general opinion was "oh no, I hope they don't ruin it -- don't worry, Amazon is known for acquiring working businesses and letting them be." I don't want new social functions on Goodreads; I get an email digest with activity of my friends, and I keep the friend list very, very short so I'm not overloaded with activity. And why on Earth does the author of the article want Amazon to get more involved with detecting bad reviews? As if their track record on their main site would provide any evidence of their being good at that!
