Woke up this morning to the following email request from the CTO of one of Hashrocket's big, important clients:

Can you give me a list of big name firms that you know are using Ruby on Rails for major projects. Need it by this afternoon for an important meeting with top management.

I scrambled together a response, including some advice from folks that responded to my query on Twitter (thx!) After some reflection, I realized that it would make a good informative blog post.

First of all, lots of people pointed me to http://www.workingwithrails.com/high-profile-organisations, which lists the following firms:

Sing ♫ one of these firms is not like the other ♫ while you're reading :)

amazon.com

BBC

CapGemini

BPN

Cisco

C|Net

EA (Electronic Arts)

IBM

JP Morgan

NASA

Oakley

Oracle

Siemens

♫ ThoughtWorks ♫

Yahoo!

In addition to the list above, there's a number of companies where I have direct, or reliably indirect knowledge of Rails adoption through my friends and associates:

John Deere

New York Times

NBC

Barclays

LA Times

Chicago Tribune

Orbitz

Google

Turner Media

Limewire

For good measure, I also mentioned http://rails100.pbwiki.com/, which tracks high-traffic consumer-facing websites that corporate-types won't necessarily recognize by name, but that for sure handle millions and millions of visits per day. The top ten list on that page (and corresponding Alexa rankings):





twitter.com [642 !!?! I thought it would be higher]



scribd.com [940]



blingee.com [1170]



yellowpages.com [1734]



penny-arcade.com [2069]



43things.com [4190]



kongregate.com [4488]



pitchforkmedia.com [4740]



projectpath.com [5041 One of the Basecamp hostnames]



funnyordie.com [5089]



What big-name companies do you know about where Ruby on Rails is gaining traction and adoption from the grassroots level on up?
