Ruby on Rails has just passed the three year mark. And, Ruby on Rails continues to impress, as popular sites such as Twitter continue to use it, as their user base grows. Ruby on Rails is evidently scalable and can take on some of the big traffic that the web can throw at a site. Plus the developer base is growing, and help is only a Ruby Wiki away from solving all but maybe your trickiest problems, which of course can be addressed in the Ruby community.

Popular Sites using Ruby on Rails:

• Twitter - The microblog that has become a powerhouse in social networking.
• Basecamp - One of the best project management apps out there, and personally used by me.
• Shopify - Ecommerce tool that builds complete websites allowing you to sell products.
• Strongspace - Secure file storage and hosting. Proves the security of Ruby on Rails.
• Crazy Egg - Get a clear picture of where your visitors are coming from and what they are doing on your website.
