Ruby on Rails gained its early popularity with startups and small companies, but it has grown far beyond that early base. Big players such as Amazon, eBay, and AOL are using Rails for some of their newer projects. And it is not limited to the consumer web: Thought works, an 800-employee global IT company, is now using Rails in many of its enterprise projects. Here’s a brief quote from the Thought works web site:

“Ruby’s elegance, along with Rail’s emphasis on Agile practices, is providing many adopters with several-times higher productivity than traditional Java and .NET web-development platforms, creating enterprise-worthy systems in many domains.”

Keep in mind that this quote comes from a substantial firm that built a large part of its reputation on Java applications.
