> Django and Nodejs is better than Rails

Why Django is better? The author seems to hook on to the concurrency aspect of nodejs(for what it was made) and compare with Rails.

Does the author know there are projects like JRuby, Rubinus, there are multi-threaded servers like puma?

One thing is very clear, the author is either writing articles for attention or does not like Rails' popularity. Classic link baiting! He has written 3 blog posts in total, all for the popularity.
