The article is a bit strange. Two different things are mixed there - goodreads as such, and generic social media issues (unreasoable dislikes, paid reviews etc). I like goodreads and do not know if there is an alternative. However, the site and app are outdated as hell, and miss some obvious features. However, if I understood the article correctly, these issues were there before Amazon, Amazon simply did not invest in the site enough to solve these issue.
