Ruby on Rails

This is might be the site with the highest traffic in the web that uses Ruby on Rails. Yellowpages.com lunched a new Beta site totally written in Ruby, both the service and the web application are written in RoR. We worked very hard to get it out, and you can check it here:

http://ngs.yellowpages.com/

Yellowpages.com receives millions of visits and page views every day. The current yellowpages.com is a J2EE application. The new RoR application will replaces the current one in the end of June.

It is hard to say who is the RoR site with largest traffic, it goes between twitter and yellowpages.com. I feel comfortable to say that we receives more traffic.

These are very interesting slides about scaling twitter:
