Interesting as I was researching this recently and certainly not impressed with the quality of the Readability implementations in various languages. Although Readability.js was clearly the best, it being Javascript didn't suit my project.
In the end I found the python trifatura library to extract the best quality content with accurate meta data.
You might want to compare your implementation to trifatura to see if there is room for improvement.
