At the most recent ArrrrCamp I gave a small introduction to Rack and Rack Middlewares in a Ruby on Rails application.

It was really interesting because I had some people in the room who knew a lot more than me about Rack and some of them who had never played with it. So we had some nice small discussions about when we use some middlewares like RACK::GOOGLE-ANALYTICS and Device. I had the feeling that in the end we had convinced a lot of people of starting to play with Rack, so my mission was accomplished.
